hello everyone, Nikolay Cherkasov, a00:00:11
tester with many years of experience and the00:00:13
founder of the Cherkasov school,00:00:17
today we have another interview with a00:00:19
novice tester with an interview with00:00:23
Alena, she has some experience in00:00:25
testing projects, but not very00:00:28
much and would like to try her00:00:30
hand at junior and00:00:32
if Do you want to participate in such00:00:36
an interview, fill out the form via the link00:00:38
below in the description or write to me in a personal00:00:41
message as Alena did, let’s00:00:44
support her with a like and kind00:00:46
comments under the video, so watch00:00:49
the interview, so00:00:51
today Alena is with us Alena,00:00:55
please tell me about yourself if you have00:00:57
any... then experience testing for whom do you00:00:59
want to be sorted to what00:01:01
level00:01:04
I want with interviewers ok engineer00:01:08
John, I’ve completed00:01:11
testing courses, that is, I want to test my00:01:13
knowledge of00:01:14
experience, I have00:01:16
little experience, I tried it inside, I worked00:01:19
from the front of the washer, I started bug00:01:23
reports and all this time, that is, since about00:01:26
December, I’ve been trying for myself from00:01:30
Nesterovo the websites of this light stores00:01:33
here are the last ones with test assignments I00:01:35
came across any site I tested lunch00:01:39
store for00:01:45
documentation I’m familiar with whether I wrote checklists00:01:48
and test cases but accordingly when the00:01:50
robots ports are super this is great this is00:01:54
great mobile applications00:01:56
had to be subsidized when no no00:01:59
this didn’t reach00:02:01
well okay then let’s start with the basic00:02:06
questions00:02:08
what is testing00:02:11
testing is a process whose purpose00:02:16
one of which is to00:02:19
make sure that the software itself00:02:21
works as it should00:02:23
meet the customer’s expectations00:02:29
the customer’s expectations how are they00:02:31
expressed in the00:02:33
form of00:02:35
requirements, that is, he lays out what00:02:39
he wants, they accept, I will describe these certain00:02:41
requirements and the egg will no longer need to be00:02:43
implemented,00:02:45
what to do if there are no requirements,00:02:49
but most likely you need to talk about00:02:52
what exactly he wants and create on00:02:56
what he already wants this person00:02:58
who collects it all moaned cumin and00:03:02
creates these requirements the00:03:05
person who collects what is the name of the00:03:10
manager manager well and00:03:14
if it so happens that there is no access to00:03:18
the customer but it happened so he may00:03:20
answer when there is no questions on00:03:22
yours maybe he won’t answer you already00:03:25
need00:03:27
to on the basis of something it compiles test00:03:31
documentation something else can be done00:03:33
where to get the requirements00:03:38
if you think like that, that is,00:03:42
envious people are probably what the company wants00:03:47
logically I don’t know there to think if there is00:03:50
some form of00:03:52
something logically at least already some00:03:56
do the main thing00:03:58
logically the main one will think, well, you’re00:04:00
right,00:04:02
it’s called using some kind of00:04:04
formal logic, yes, that is, there are things00:04:07
that we know a priori and we don’t need00:04:10
this to be clearly stated in the00:04:12
requirements because let’s say if we00:04:14
test an online store, we roughly00:04:16
suspect that in all00:04:17
online stores have a shopping cart, that there is a00:04:20
payment function, there00:04:22
may just be some nuances we00:04:24
may not know, but nevertheless, that is,00:04:27
we can take the requirement from similar00:04:29
services, we can invent requirements out of our heads00:04:32
that correspond to the00:04:34
general accepted approach, for example, to an00:04:36
online store good good00:04:41
you say that one of the goals00:04:44
of testing is to compare expected00:04:47
behavior with actual behavior, and what other00:04:50
testing goals do you know about the00:04:52
purpose of testing, that is, even tell us00:04:55
whether the product is ready for release at all,00:04:58
that is, how ready it is,00:05:01
well, of00:05:03
course, I didn’t name the goals00:05:08
most likely as a consequence of the fact that the00:05:10
expected and actual results, that00:05:12
is, to minimize bugs, that is, so that there00:05:15
is as little as possible00:05:17
preventive such a method, that is,00:05:20
on the one hand, we can always find bugs and00:05:22
report them, and on the other hand, we00:05:24
can somehow, as you say preventively00:05:27
do so that there are00:05:29
fewer bugs and00:05:30
what does this involve such as magic00:05:33
when we are warm in advance00:05:43
but00:05:52
in fact, that is,00:05:56
when you test a program you not00:06:00
only spoil the bug, but00:06:03
you can also00:06:05
give feedback to the00:06:08
development team and, for example, point out00:06:12
that here in the system, specifically, some00:06:14
part of this system may not be00:06:18
very well developed, there will probably00:06:20
be bugs in it, because it00:06:22
seems to you that she is right, then this is exactly00:06:27
how you can help development00:06:31
in advance, pay attention to those places where there00:06:34
may initially be bugs that is, there00:06:42
may be feedback for the development team, and00:06:46
there may also be feedback for the00:06:49
team not in technical terms, but in00:06:53
terms of what the customer initially wanted,00:06:55
that is, in addition to specific requirements,00:06:58
we can see what the customer, for example,00:07:01
would like, well, he has the main00:07:04
idea of a product, let’s say during the00:07:07
development process you see that for some00:07:09
reason00:07:13
parts of the functionality are developed first,00:07:15
some are important and some are not important, and you00:07:19
can also give feedback and00:07:20
say so guys, we don’t seem to have any bugs,00:07:22
everything is correct, but here’s our development00:07:24
something- that’s not what he’s focusing on, but00:07:27
the customer wanted something00:07:29
else to be done first and this is also like00:07:33
one of the attributes of testing is00:07:36
okay00:07:39
okay let’s talk about the00:07:43
type of testing you know some00:07:45
classifications of types00:07:48
well and standard functional00:07:51
functional manual automated00:07:54
testing00:07:55
that’s00:08:00
not there this is from Michael Big, that is,00:08:02
unit testing,00:08:05
integration testing of00:08:07
already systems, this is stern and testing during00:08:10
acceptance testing itself,00:08:13
well,00:08:17
well, there are many different00:08:20
classifications that we have here and00:08:23
acceptance modules are integration, but00:08:25
acceptance modular integration00:08:28
system is, in principle, we usually00:08:31
call in theory levels testing,00:08:33
well, as a rule,00:08:35
then tell us in more detail what these00:08:37
levels are about with the00:08:39
most blinkers, this is unicast and that is,00:08:43
some specific00:08:45
one module00:08:46
is being tested, and nothing else is being00:08:49
touched on integration, also like00:08:52
the interaction of two or more modules with00:08:53
each other, the system is already being tested from00:08:56
all cavities of the00:09:01
system tested on the E100 briefly00:09:03
accepted, that is,00:09:06
either you are the customer or potential from00:09:09
those who will be users, they are already00:09:11
testing how inconvenient it is for them like them, is everything00:09:13
okay there, does it meet00:09:15
the requirements00:09:18
well, you're like a pea, it's in syrup when00:09:22
I think that at what levels of testing00:09:23
you will be the most00:09:26
most likely to act either modular and00:09:29
integration modules for the time being this00:09:32
skill will affect00:09:34
the module it will most likely be the00:09:36
developers or both00:09:40
the system00:09:44
and acceptance ones sometimes it’s good00:09:48
that you don’t know about the boxes of multi-colored00:09:52
balls and the white00:09:57
black box and then when we don’t go into the00:10:02
system itself, of course we don’t go to such a thing,00:10:04
I don’t know what code is written like a capa for this00:10:07
building, that is, this is basically the00:10:10
customer’s requirement of a00:10:14
white box, as we already know, while00:10:18
you are still writing everything, the code itself understands this00:10:21
logic, and that is, we ourselves from the posters are00:10:25
absolutely correct, everything is correct Have you00:10:28
ever heard about a glass box,00:10:32
it’s the same as a white box, it’s just that in00:10:35
some books it’s called white, it’s the00:10:38
same thing,00:10:41
but if he asks, now you know that00:10:44
glass is00:10:47
good, there’s also a tricky gray box,00:10:50
which is very difficult to explain to everyone.00:10:52
I’ve heard about this.00:10:54
it’s not a completely clear boundary, it seems00:10:57
like you need to partially00:11:00
know something about the code, how much of it you need to know is00:11:02
not entirely00:11:04
true, it’s not clear to anyone, so00:11:07
you can read 10 articles and they will00:11:09
always differ from each other,00:11:11
okay,00:11:14
some non-functional types00:11:16
of testing are you can you name those that are00:11:19
not directly related to00:11:20
testing the main functions of the system00:11:27
at home,00:11:30
for example,00:11:33
graphical user interface,00:11:35
how does it look like it corresponds to the00:11:38
layout,00:11:40
browser testing, that is, we actually have00:11:43
two pints of this application, we00:11:45
open a holiday of browsers like google00:11:47
chrome, for example,00:11:49
mozilla00:11:52
microsoft, if we look at what is00:11:55
really everything opens for us, everything00:11:57
works well on different platforms,00:12:00
for00:12:07
example,00:12:10
installation, that is, but it will most likely00:12:12
be closer to a mobile application,00:12:14
that is, that it is really an application that is being00:12:17
restored, that for us it00:12:19
is updated, everything is fine and that we00:12:21
can hit it,00:12:27
localizations, that is, that we, for example,00:12:32
write well, as if for Russia, and even00:12:36
inside it seems to me that Russia itself00:12:39
has different time zones, having found that00:12:41
the time is displayed correctly,00:12:46
the localization is not quite the correct00:12:49
time zone, rather00:12:54
in Russia we have adopted one format00:12:57
for displaying the date because for Russia00:12:58
you are a wall localization is unlikely to be suitable00:13:00
unless you check the00:13:03
language of our republics, there is00:13:05
some kind of Tuvan or Permian dialect like00:13:07
hryvnia, but more if we are talking about00:13:11
time, then it is the format for displaying the date00:13:14
and time, here we are, for example, in the USA,00:13:19
which is customary we have a 12-hour00:13:22
day and m and p m and00:13:26
in Europe, let’s say, well, in particular in00:13:29
continental Europe in Russia we have a00:13:31
24-hour way of displaying time,00:13:33
so accordingly, when switching00:13:35
locales, the display format should00:13:37
change the date format, we have accepted day00:13:40
month year and in America accepted month day00:13:45
year here and or even year day month this is00:13:50
often used except for the format for00:13:53
displaying the date and for example the language what00:13:56
else can change what do you think00:13:59
if for example the same00:14:02
clothing store is at least a currency that is, there00:14:06
were before each country and it is different this00:14:10
dimensional grid00:14:12
because it is also varied00:14:17
probably good enough in principle00:14:21
okay well have00:14:24
you ever heard of such types of00:14:27
testing as smaug appreciate and regression00:14:33
heard00:14:36
able testing that is, and00:14:39
only superficially like testing a00:14:41
functionality build without going00:14:44
into depth that God is more or less00:14:46
stable drive it's about the same00:14:49
thing but it's already going deeper that00:14:51
it really works00:14:52
the functionality of us is correct that's what it would have00:14:56
left me already00:14:58
stable00:15:00
regression testing00:15:03
testing when we release a new00:15:06
feature we look at everything else that00:15:08
was written and it's tested We are00:15:10
stable and haven’t gotten anywhere, that everything00:15:13
works, everything is fine, it’s somehow interesting that00:15:16
the rule of the word stability is through all three00:15:18
types of testing, and in the end I still don’t00:15:20
understand how they differ from each other00:15:22
if they all check stability and00:15:24
everything is fine with us and stable00:15:27
if you look at the smog and the balls they00:15:29
check one parable about00:15:33
[music]00:15:39
how they differ from each other then they00:15:42
themselves check one feature and give a00:15:43
stable smog this is a superficial00:15:46
check salt this is a more00:15:48
in-depth check of the program00:15:51
there is no functionality but smog is well00:16:01
yes00:16:03
what is the difference I was able to evaluate and00:16:09
that they can do it faster, then they write the case00:16:15
here and check, well, literally,00:16:18
like the surface, that everything works after00:16:21
all, everyone, that is, the00:16:23
application as a whole works well, and sanity is00:16:27
probably about specific functionality,00:16:30
that is, it was able to check in a broader way, we00:16:33
check that the entire application works more or less00:16:35
in principle; this is what we need to00:16:37
conclude that we can, in principle,00:16:39
start testing sanity;00:16:42
this is checking specific functionality00:16:45
in depth; this can be either a new00:16:47
functionality that has just been00:16:48
written or some kind of optional functionality based on a00:16:51
certain criterion That’s exactly the00:16:54
same, and when we conduct sanity, we do not00:16:56
conclude that, in principle, everything is00:16:58
fine, we conclude that the00:16:59
specific functionality00:17:02
works great and is ready to be00:17:04
added00:17:05
to the general program, a piece of the general00:17:10
regression of00:17:12
Oreshkin of the same thing, when00:17:15
they add functionality again, we00:17:17
see that everything else00:17:21
also works correctly, and everything else00:17:25
that the rest of the steel sent00:17:27
the rest of the functionality,00:17:30
well, we sort of checked00:17:37
the nationalities, added a new one and see00:17:40
that the new functionality did not affect the00:17:42
operation of the old functionality,00:17:47
which means we will burn out the old00:17:49
functionality in the process, but00:17:56
so that when adding new ones,00:17:59
work the old one,00:18:01
evaluate it, but then why00:18:06
1 functionality is it from after mine, how does00:18:10
it interact with the steel ones, as00:18:12
soon as she does it myself and then on the roof00:18:15
regression when we check the new00:18:16
functionality of the side, we check it, so here00:18:18
we are00:18:24
[music]00:18:30
but this you are a little mistaken in general,00:18:34
regression is exactly when we00:18:36
check old functionality00:18:38
that does not belong to the new one and we00:18:41
check that the old functionality00:18:44
works after we added00:18:46
the new one and before that we check the new one within the00:18:49
framework of appreciate testing, that is, we00:18:53
checked that everything was able to quickly00:18:55
more or less completely holds, then00:18:59
we check the latest functionality00:19:01
and then we check everything else within the framework of regression,00:19:05
why do we need water, in principle, such a00:19:07
three-level approach, you know, a00:19:11
separate one could connect immigration,00:19:13
they would take everything from the cases, they would immediately shove00:19:17
thousands there from the sketch to and go through00:19:19
what's the difference with max inter sinner, well,00:19:23
it's like step by step 5 first we00:19:25
carry out smog then we ourselves often lipstick00:19:27
regression why is everything step by step body00:19:30
why and so but if we00:19:35
write everything it seems to me we just might00:19:37
miss some bugs and00:19:40
errors00:19:42
something might not work correctly and00:19:44
then all this is in this back in the opposite00:19:46
direction to dig where that she goes00:19:48
after the salary there is an error in the reverse00:19:51
side of the c-class card, well, look, we00:19:54
have tass cases, they are already written, they are already00:19:57
written, that is, we cannot00:19:59
let anything go, we have from the case we00:20:01
go through them one by one, let’s say we have00:20:03
1000 thousand cases, I don’t know about this, 50 are silent00:20:07
there, 200 at the summit and there 750 are regression, so00:20:11
we have a bunch of skism and for some reason00:20:14
we highlight the smog regression and for some reason00:20:18
we go through them specifically one by one according to00:20:20
some logic that's why we do this00:20:22
if for example we end up00:20:24
passing all the checks anyway we had thousands of00:20:27
kitty-kiss we would call them a bunch of tess00:20:29
cases on me here you sit down and walk one by00:20:32
one why do we need these levels the ticket00:20:35
is probably connected development and00:20:39
that is, it is written well, as if00:20:42
development is gradually going on, that is, some kind of00:20:47
functional one was written,00:20:50
then put it then while solaris tests it,00:20:53
writes new nationalists, we are already checking and00:20:59
have carried it out accordingly, so it goes from the smaller to the00:21:02
larger,00:21:04
it gives out checked everything is fine00:21:07
Everything works stably for us, that is, we take00:21:10
the next one, while we look at the next one,00:21:13
they write a trace, well, according to the00:21:15
next ones, and just get out of the way, we’ve00:21:18
already00:21:22
checked the second functionality, we’re00:21:24
doing regression testing that the00:21:27
functionality is set to everything is00:21:28
fine, and so it’s like, well smell .00:21:34
During the development process, you correctly00:21:36
described the types of testing, they are indeed00:21:39
used in turn every time00:21:41
we come up with a new00:21:43
functionality,00:21:46
but the essence of why we still divide 3 you didn’t00:21:49
name, look, the simple fact is that00:21:52
we do00:21:55
n’t always get a stable build in the00:21:56
buildings let's add its00:21:58
functionality, sometimes after adding00:22:00
new functionality the program does00:22:02
not open at all and our task as a00:22:05
tester is assigned to us; we receive the00:22:07
next build to00:22:08
make sure that the build is generally00:22:11
worthy or available for00:22:16
large-scale testing and therefore we need to highlight00:22:19
individual cases that will simply check at the top00:22:22
that the program, in principle,00:22:24
works because if it doesn’t work in principle,00:22:26
there is no point in00:22:28
carrying out or hernia and delving into what00:22:30
complex cases of old ones and it doesn’t00:22:33
work,00:22:34
appreciate it, we need to check the latest00:22:38
functionality, as a rule, why do we00:22:40
check the fresh functionality00:22:43
because I just added it and00:22:46
statistically the maximum number00:22:48
of bugs and, well, most likely there is something wrong with it00:22:50
because I just added it and00:22:52
we check it secondarily after00:22:55
you say that the program00:22:56
basically works and is00:22:58
regression-based and we check it00:23:00
last because there is00:23:03
no chance of finding bugs in there are00:23:08
much fewer regression tests because regression00:23:11
tests are something that was once valued, but00:23:15
in the previous development cycle, we00:23:18
already checked it once and then we00:23:19
just put it all in a suitcase and keep it all,00:23:23
and that’s why00:23:24
some companies sometimes00:23:26
even refuse regression to00:23:30
save money time or they say, but you00:23:32
check the regression and only if there is time00:23:34
left,00:23:35
therefore, precisely in order to00:23:37
prioritize our workload,00:23:39
we come up with these levels and00:23:42
keep everything in our heads where we are now on the00:23:45
project, where our latest feature is now,00:23:48
in order to understand how deep it is today00:23:51
we have to test and this is very00:23:54
important, this is the groove from the practical point00:23:57
of view when you will work,00:23:59
so we are discussing this in depth,00:24:02
this is quite a practical00:24:04
question,00:24:05
okay, but there is also a division00:24:09
from cases into positive and negative00:24:12
checks, you know what the difference is,00:24:16
positive checks is how we00:24:18
expect, that is, we are not trying to break00:24:21
the system, we, since the user must00:24:25
behave, we00:24:27
check, so let’s say, friends00:24:31
behave, the system names are already in the negative, that00:24:35
is, we are non-standard and begin to own00:24:39
checks, so00:24:41
ideally, of course, so that if we don’t00:24:46
know, we write a00:24:47
case like this so that00:24:51
the program works00:24:54
positively, as if not about further, let’s00:25:01
say00:25:03
water, a positive attitude is directed, that is,00:25:07
how the system works under normal00:25:10
conditions, that is, normal, as if there00:25:12
will be all the values within the permissible limits of00:25:16
accepting fields there, for example, negatively,00:25:20
this, on the contrary, is already what is supposed to be00:25:23
shouldn’t work, we just don’t00:25:27
check how the system shouldn’t work,00:25:29
it’s interesting, what is our expected00:25:31
behavior in negative scenarios then00:25:34
that the computer explodes or smoke comes out00:25:36
or Korea00:25:38
if we look at a calculator00:25:42
[music]00:25:43
divide by zero we can’t have this be a00:25:45
negative check, that is and the soul of water00:25:48
with an error, if we have a division by zero,00:25:50
respectively, this is already a defect,00:25:52
then it knows that as if a negative check is00:25:55
not dependent, as if a00:25:57
positive result is expected, we have to00:26:00
set our error, but00:26:02
in fact this is another thing, but with00:26:05
positive ones, that is, this means it00:26:10
gives 4 and00:26:12
here you correctly named the example and not in00:26:16
theory it didn’t work out well to write the00:26:18
correct answer would be that we00:26:20
expect that the user who00:26:22
uses the system will either do00:26:26
what00:26:27
the system implies or something that00:26:30
contradicts the logic of the system the system00:26:33
itself is always00:26:35
adequate should react to this00:26:37
only if the positive scenario00:26:40
is some kind of new, well, what is the00:26:43
positive scenario, there was a00:26:45
purchase in an online store, something else, and00:26:47
if the user behaves as the00:26:49
system would not want everyone to lead there,00:26:51
some kind of error the tooltip is shown as00:26:54
it pops up or the system simply does not00:26:56
react, anything can happen, why do00:26:59
we need such a division, what do you think,00:27:02
but it seems to me that it is necessary because first of00:27:07
all it carries out positive00:27:09
checks to make sure that at00:27:10
least a functional00:27:12
sedan is really working correctly, the system00:27:15
reacts only00:27:17
then negatively is carried out that is,00:27:20
finding bugs if everything is good,00:27:22
positive and nothing shows up,00:27:25
you just proceed to the negative ones so that you can00:27:28
already check to exclude the already negative00:27:30
scenario, why, well, let's check the00:27:33
negative one first and then check00:27:34
the positive one, and what's the difference,00:27:37
but this may probably even be related to that00:27:39
that initially we don’t need to find00:27:41
errors, we don’t need to break the system,00:27:44
but at least make it worse, that it00:27:47
meets the requirements, that’s why,00:27:52
according to the requirements, this is00:27:53
positive, basically positive00:27:55
positive checks, that’s why00:27:57
they are carried out first, well, something00:28:00
like this, in fact, a negativity scenario00:28:04
can be indicated in the requirements for00:28:05
example, what00:28:08
error should be shown in the case of a00:28:10
negative one? In fact, the problem is00:28:13
that there are an infinite number of negative scenarios;00:28:15
you can come up with them, come up with them, come up with them, come00:28:16
up with them, the00:28:18
user has some kind of keyboard shortcut and00:28:20
entered that he threw some kind of virus at the input, it’s00:28:23
not something else and this is forever forever00:28:25
forever and you will do this endlessly00:28:27
and in the end, instead of00:28:29
testing the program, you will endlessly00:28:31
come up with a negative scenario, so00:28:33
in the industry they usually write the most00:28:36
frequent and most basic00:28:39
negative scenarios, for example, the user entered00:28:41
the wrong login or password, but this is a00:28:44
classic yes that is, how can you not00:28:46
provide for such a case and you will,00:28:48
of course, check these scenarios after00:28:50
you check the positive scenario,00:28:53
but there will always be some point in00:28:55
the project where you will stop00:28:58
to come up with a negative scenario and then00:29:00
move on in testing, that’s why so as00:29:03
not to endlessly generate00:29:05
negative scenarios because00:29:09
no matter how many of them are generated, there is still00:29:10
a user who will come up with something that you ultimately00:29:12
won’t provide for and that’s why it’s not worth it,00:29:16
super ok00:29:20
techniques, then from the design you know any00:29:25
equivalence classes,00:29:30
state transition boundary values are there and tested in pairs00:29:32
for there00:29:34
I didn’t use pairwise ones, okay, let’s start with the simplest ones,00:29:38
here’s equivalent divisions00:29:41
worth00:29:42
equivalent divisions such classes00:29:45
within which the system reacts00:29:48
in the same way and to any value inside00:29:51
this class, so an example of a class can come out, for00:30:02
example, we have an input field00:30:05
taxes accept a value,00:30:09
for example, only Cyrillic and Latin00:30:11
no other forces, that is,00:30:14
according to how popular00:30:16
it will be the first00:30:18
Latin and Cyrillic00:30:20
characters and another class it will be the rest00:30:24
sleeping symptoms of numbers and so on until it is00:30:28
decided except for the Latin00:30:30
Cyrillic alphabet they do not accept anything from where will the00:30:32
numbers come from00:30:39
no this other class of Cyrillic alphabet in00:30:42
Latin portraits you say you00:30:44
say let's say from from polyvoda00:30:46
which accepts only Cyrillic alphabet into00:30:48
Latin alphabet and00:30:50
then you say here is an example of how we will00:30:53
work here we have an00:30:54
equivalence class let's say Cyrillic alphabet well00:30:56
everything is correct up to this point there00:30:59
is another equivalence class then numbers and00:31:02
letters00:31:03
symbols00:31:07
special characters there as the scooter doesn’t know.00:31:15
you shouldn’t accept and anything that we00:31:18
see from it, as if the system should Krishna00:31:21
didn’t understand this is the valence class for00:31:24
negative scenarios00:31:28
good00:31:36
good in fact the Cyrillic and00:31:39
Latin alphabet they also cannot be the same00:31:41
class to valency this is true these are00:31:43
keyboard symbols but since there are two00:31:45
different alphabets, this is not separate, they are00:31:48
not 1 lat, it doesn’t matter correctly, a good00:31:52
answer is fine,00:31:54
why do we need such an approach,00:31:57
why do we need to enter some set like a spikelet of valence, yes, let’s say there are00:32:02
symbols for input, what’s the point of00:32:06
minimizing the number of tests, since it00:32:09
can’t be limited in time,00:32:12
so checking each character seems to be there00:32:17
without knowing if by length, that is, you are the00:32:20
same every time, we will have very, very00:32:22
many tests, thanks to this, how do00:32:26
we do the selection inside this class, that00:32:30
is, accordingly, if it reacts the00:32:32
same system, that is, we00:32:35
will have much fewer tests, and why will you00:32:37
show me apples 130 you00:32:39
say everything correctly, everything you say is correct,00:32:40
but it is necessary and specifically what will00:32:43
save time here, so we declare for ourselves00:32:46
that we have input data,00:32:48
let’s say alphabetic symbols and we00:32:51
use the technique of valence00:32:54
separation,00:32:55
which in the end, like this, we have a00:32:58
real input field, take into account the alphabet,00:33:01
so mine is here, here is an example from cases,00:33:04
to understand how they save us00:33:07
time and quantity,00:33:12
for example, in the input field we enter there00:33:16
in Cyrillic words, let’s assume any, no matter00:33:20
what, can’t be cleaned and on the side in00:33:23
Cyrillic,00:33:25
accordingly, our system should be00:33:27
responsive, everyone logged in well,00:33:30
the following there we take if we have an empty00:33:34
value, that is, our system says00:33:36
that it’s empty, I won’t drag you, but roughly00:33:39
speaking, this is it and this is a negative test like00:33:43
you plus 1 more out of 100:33:46
character and we don’t know we wrote there!00:33:50
. , . . and again he systematically says, well, no, it doesn’t00:33:55
matter, we can even write one sign00:33:57
there, two or three, on any small article, he00:34:00
won’t miss it, accordingly, as if our00:34:04
tests are being reduced, the tests are much smaller00:34:07
than we will be letter a letter p letter you00:34:10
there and so on, letter na checks we00:34:14
can do an infinite number of test00:34:17
cases and so we just entered00:34:22
here I understand what you are saying, just the00:34:25
most important thing is to say that we don’t00:34:28
need and from each class to valence we00:34:30
check all input data, that is,00:34:33
let’s say 5 characters, we don’t need00:34:35
to check all the articles we need urgently00:34:37
check one or more,00:34:38
depending on how many00:34:40
letters we have minimum for the input, we don’t need to00:34:42
check all the letters of the alphabet, check a00:34:45
couple yourself,00:34:49
it’s good and00:34:52
give ethanal about the analysis of the boundaries of the00:34:55
value, let’s talk about what it is, why it is00:34:57
needed about the00:34:59
boundaries of the boundary values, it often happens00:35:02
that on the border00:35:03
errors appear therefore and there are such00:35:07
as such a design technique and if we00:35:10
take for example the same pain and here and00:35:12
and00:35:13
it accepts from spots for example up to 1500:35:17
characters00:35:18
inclusive so we must check with00:35:21
us the system is like a bonus there for example00:35:24
two characters of it if from five to ten00:35:30
then these are four symbols of the same meaning00:35:33
you say he was given a chance theory then00:35:35
we dive in00:35:37
how many checks we usually need00:35:41
in accordance with Kovalenko’s technique and00:35:43
analysis boundary value00:35:45
interval00:35:47
here we have four so name what00:35:52
they are 4 for example00:35:56
border minus 1 value and the upper00:36:00
limit the purpose is00:36:02
good excellent and now we can00:36:07
give an example here we have an interval00:36:09
there from five to ten what specific00:36:12
checks will you use00:36:14
checks for four characters by 5 characters00:36:17
by 10 1 cm00:36:20
this will be put on 411 this will be00:36:24
negative clerk and if there is an interval from00:36:27
1 to a million, how much will we have00:36:33
one million00:36:35
million one00:36:39
if there are 10100:36:44
correct correct then the strength of this00:36:47
approach is that no matter how long00:36:49
our check interval will always be the00:36:51
same, here in fact there is a00:36:53
philosophical question how many should there be00:36:55
be at a minimum where it is written 4 somewhere it is00:36:57
written 5 that is, let’s say I read something00:37:00
else inside the interval, you need to take a00:37:02
random value so that00:37:04
everything works there,00:37:06
but that’s good, true, super00:37:10
okay, let’s talk about the00:37:14
test in the documentation, that is, the plan00:37:16
had to be once - something to write and00:37:19
about00:37:21
40,00:37:25
I understand what I read that this is a00:37:30
document where we have an entry point for00:37:32
testing the project, the race is00:37:35
registered in the environment in which it will be00:37:37
run, perhaps there is a version beat as it00:37:42
were, these are all the nuances,00:37:45
you said correctly approximately about the00:37:48
entry points - output these are the criteria for the beginning and00:37:51
end of testing00:37:53
about the environment correctly that we00:37:55
are selecting my environment and what else are we? well, there00:37:57
may not be a build version of the VTS plan yet,00:38:00
but they removed the exact one on the transport world of00:38:01
Sybil, for example, and we can still indicate something there00:38:11
[laughter]00:38:17
well, here we go 5 with your fingers00:38:21
there is formally an00:38:24
industry standard on how to write it out, but there is a theory,00:38:26
there is a lot of things you can do and00:38:29
testing can be specified, you can specify00:38:33
to write down in00:38:35
which place, let’s say sprint, how the00:38:37
stubble driver will be used, that00:38:39
is, there is a lot there, well then I recommend00:38:42
reading it separately, then at the end then I’ll00:38:45
tell you00:38:46
what the criteria are. at the end of the00:38:48
tester we are specific, okay00:38:52
test case checklist what is it and00:38:55
why are they needed what do I include00:38:58
h cell is a set of checks that is, without00:39:02
going into depth a00:39:04
set of checks or a case is already more00:39:08
expanded00:39:09
such checks where we already have and we have the00:39:13
reproduction steps and what the expected result00:39:19
looks like checking in the checklist, here is the00:39:22
check itself, what is in it and00:39:24
[music]00:39:26
poisoning, we like to tidy up, we00:39:30
need it, we have a sketch, you say the00:39:31
bag and expect the result, but there is probably00:39:34
some other name there so you can00:39:37
identify00:39:40
what a checklist is this is a check, a list of00:39:44
checks, checks, a check list,00:39:46
respectively, each check,00:39:49
each check contains00:39:52
some different fields, or else to00:39:56
go check it myself,00:40:00
I’ll briefly and briefly as a check what I00:40:03
check00:40:04
personally, mine is without going into detail, that’s00:40:12
usually one name in itself, yes, there’s some00:40:14
kind of crap that works, this00:40:17
registration is successful there, it’s00:40:20
so short, without any complex ones, but00:40:30
why do we, in principle,00:40:35
need these candles and crosses for the same thing to describe testing scenarios, that00:40:39
is, it’s like for the same thing00:40:41
necessary but has different complexity of description,00:40:44
depth, why do we need such a problem, why do00:40:46
n’t we use one thing, most00:40:49
likely you will also be connected with00:40:53
me by the development itself, what is00:40:57
related to the00:41:00
project00:41:02
is used there somewhere, you will need to00:41:05
check everything thoroughly, then it will be00:41:08
accordingly pier cases00:41:10
are carried out if you work somewhere, but00:41:14
as if one tester understands what00:41:16
you will be doing there and it’s not a very00:41:20
large project, then it seems to me that you can00:41:23
get by with the checklist itself, it00:41:32
depends on the size of the project, yes, let’s say00:41:35
if00:41:37
you one is acceptable and you don’t need00:41:40
to describe any complex checks to anyone,00:41:42
it’s like the most taxing course, then you can00:41:44
make checklists and that’s right, if00:41:49
you’re not alone in the project, there are several of you, then it’s better, that is,00:41:53
to do with it, the project is00:41:57
quite large and requires but00:41:59
I can write for myself because it00:42:02
will be clear to another person if he00:42:05
takes the same Sanych sheet, he may not00:42:07
understand what I wanted to say by this, no00:42:10
I did the test for understanding00:42:12
for team work, so let’s say it’s true that00:42:15
the beads understood each other everything is correct00:42:18
and also somehow you think what can00:42:21
influence the choice besides the size of the project00:42:25
and let’s say the complexity doesn’t00:42:34
know doesn’t come was00:42:38
the amount of time let’s say even00:42:41
if the project is very complex but you00:42:44
just don’t have time to write a test of00:42:46
the documentation you need to test but for00:42:48
yourself you somehow want to secure some then a00:42:51
testing plan for someone in some kind of00:42:53
suite so that at least you can make notes somewhere and00:42:56
you yourself don’t get confused, something you’ve already00:42:57
passed that you haven’t passed here, you00:42:59
would have to use a checklist, willy-nilly,00:43:01
because you’re faster than a scribbler, and if there’s a00:43:04
lot of time if the project is so00:43:06
sticky, it always gives, I can if it’s a00:43:09
sprint and long you don’t have every 200:43:12
weeks you have a release every two months00:43:14
there, as a rule, you can write in more detail on the board and with and00:43:16
so on00:43:19
good00:43:21
norms super00:43:23
[music]00:43:24
bug report what is that all includes00:43:29
bug reports on you includes these ideas, that00:43:33
is, the name, what the name is, what where00:43:36
and under what conditions happens so that00:43:39
another person who will00:43:40
fix it understands00:43:43
someone the same beginning, so let’s say00:43:46
a flash drive, it looks like put cases on this00:43:48
that this environment00:43:50
is written, maybe what - the preconditions00:43:52
are the same steps of reproduction, but the00:43:57
bug report differs from the test case itself00:44:01
in that there is an actual result,00:44:03
that is, what do these steps lead to,00:44:06
that we see it, which does not suit us,00:44:08
but accordingly, there is already this there00:44:12
may not necessarily be a00:44:14
video application, for example, a tavern is produced or a00:44:18
screenshot of where this tank is also located,00:44:21
and in itself, as if this is the seriousness00:44:24
of this bug,00:44:25
that it can be critical there, it00:44:28
can be very tank, but then it’s insignificant, it’s00:44:31
still very important, well, not critical, yes without00:44:35
it maybe a bug report, well, also, but for the00:44:37
moment who is working the author00:44:41
because the author is usually a00:44:43
tester we whom he will00:44:44
return in case of anything and which there00:44:46
will be questions00:44:50
generated behavior should also be00:44:52
mentioned yes I understand you said the00:44:54
same Poles essay but still said00:44:56
almost00:45:03
everything else is normal in principle and00:45:05
true indeed, and00:45:08
regarding seriousness this is a dangerous word00:45:11
because in theory there are gradually00:45:14
the words priority and there is seriousness and00:45:18
let’s say in fat this field is called00:45:21
priorities of seriousness there is no but in00:45:24
some microsoft system for00:45:26
storing tickets there there is a00:45:29
priority to seriousness, there is a whole philosophy of how00:45:32
to divide these concepts00:45:34
accordingly,00:45:35
you say in sports there is seriousness00:45:39
only we can00:45:42
or tula prices or maybe obscurity00:45:46
only00:45:50
priority priority shows us how00:45:52
urgently we need to fix this bug not in chapters,00:45:55
it also exists, that is, how00:45:58
important it is this come shoot this00:46:02
always it seems to me there is this00:46:04
seriousness as if this is already this00:46:07
is completely different this is how00:46:09
seriously it affects the functionality everything is00:46:14
correct everything is correct you say that everything is so00:46:16
simple but now yes there is in jiri in the system00:46:20
that uses 90 in the center of cases00:46:22
there is no separate field of severity therefore00:46:24
when you build a priority, you immediately00:46:27
take everything into account and how dangerous it is,00:46:29
how much of a hindrance it is, but in fact, most00:46:31
often, if the tank breaks the floor of the system,00:46:34
then usually it has a high priority,00:46:36
but usually it only happens in case00:46:40
of before, but nevertheless, good, great,00:46:45
so00:46:47
let's talk about the00:46:49
life cycle of a bug report and what00:46:52
happens to a bug report am in an00:46:56
average system after you have00:46:58
started it there and00:47:00
I have already discovered dacia enamel, I assign it and00:47:05
send it to the developers so that he00:47:09
fixes it, so let’s say it’s true that00:47:13
he also reproduces the interior of his exe,00:47:17
so he doesn’t send it back that is, I’m already00:47:21
looking at all the affairs of the hour, the pearl00:47:24
tank closes and the real one is like this,00:47:30
but it’s not always ideal,00:47:34
what can be and is not so, it happens that00:47:40
maybe it’s not a bug, it’s like the00:47:44
behavior of this feature,00:47:52
I’m checking, it00:47:55
happens that it it doesn’t reproduce00:47:58
dogs, it reproduces for me and then I need to00:48:02
look here or at the checkout soared, I00:48:05
look to see if everything is really00:48:08
correct, I did it, we also have it, then most00:48:12
likely we need to look with the00:48:16
developer here, the conditions are00:48:18
the same, we have the same immersion if we have a version of the build00:48:22
we are different accordingly and00:48:24
cannot understand each other, it00:48:28
seems to me that in the extreme case if00:48:30
everything seems to be perfect, you00:48:33
will probably need to come here and00:48:36
ask for advice, everything is correct, we will00:48:40
get to the lead correctly if there is no team lead,00:48:42
we can also write here and say that there is00:48:46
such a guy here and00:48:48
he then a person and not a person00:48:51
who is responsible for all the products will say00:48:54
either to the developer, come on,00:48:57
try to find the tank to fix it, or he00:48:59
will tell you okay, the tank is not scary, you think that it is00:49:03
not terrible, put it aside where00:49:05
they will close it, but you, as a00:49:08
testing professional, are not you’ll forget to make a00:49:10
bunch softer in the comments there, they told me00:49:11
whether to postpone its closure there, in00:49:13
fact, he acted so let’s keep it00:49:15
in mind,00:49:16
well,00:49:19
we00:49:21
thought about when everything is good with us,00:49:23
then when we have a bar, at first the00:49:27
developer writes it doesn’t play00:49:29
in this, they decided more notes tank like this is a feature00:49:32
and what else happens what do you think00:49:35
in Natsik’s life bug report and when a00:49:38
duplicate is most likely00:49:41
years old you00:49:43
also need to check here it’s captivating to00:49:46
which gods and don’t give a [ __ ], well, what if this is a00:49:50
bug that initially how to indicate that a00:49:51
duplicate is closed or open and00:49:55
if it is closed, which means it re00:49:58
-opens, as in the opening, it does00:50:01
stand in front of you once again baking00:50:05
is carried out,00:50:07
if it is open, then00:50:11
it is possible that the00:50:14
whole is the original one that will come back here in the00:50:19
first thing we find out is that there00:50:21
really was a duplicate because00:50:23
sometimes the developers believe in me00:50:25
it seemed like you saw something similar,00:50:28
please look through the eyes of 150 open bugs00:50:31
and this is what you will find there, that is,00:50:33
this option does not suit us based on the00:50:34
quotes, we say let’s click00:50:36
the link to the double so that we do00:50:39
n’t deal with all this, but if there is a link,00:50:42
you really check first Is it a00:50:44
duplicate because it might also00:50:45
seem like, well, let’s say there’s a tank in the00:50:48
login field, you check the password field and00:50:49
they have different validity, not page 1, they’re00:50:52
nearby, but still, if you00:50:55
agree that there really is a duplicate,00:50:57
you, as you said correctly, look at00:50:58
the status here this original bug00:51:00
that was then if it is still open then yes00:51:05
you eat yours with Lenkov, just00:51:06
add information and close it if the00:51:10
original bug is already closed as00:51:12
it was fixed or something else you do00:51:16
as is customary in your project or you00:51:18
Perry open it original tank,00:51:21
if possible, you00:51:23
need to add the same information, or you00:51:25
change the status of your duplicate to nil, just00:51:28
throw a link to the old grandmother and00:51:29
say, well, it already happened, so let's00:51:32
fix it and it will be easier for the developers, here you00:51:34
already need to see how the team is good,00:51:37
super00:51:38
okay,00:51:41
let's talk then That’s what you00:51:46
were talking about, that you tested in the application and00:51:51
you have some experience in this. Can you00:51:54
tell us in principle the features of working00:51:56
in the application and00:51:58
what we need to build on when we00:52:00
choose different types of testing, yes, that00:52:03
is, but what should we pay attention to00:52:06
specifically? application, as opposed to00:52:07
native or hybrid ones, when we00:52:11
test00:52:15
I have when I look at the application00:52:18
web applications tested it will be00:52:20
restored for me, I think00:52:23
registration and authorization,00:52:27
but it also started as if there is so I’ll say00:52:31
that00:52:33
I broke everything down for myself into modules, it’s00:52:36
just understandable, but if we, in principle,00:52:39
approach from how these taxes00:52:41
work to a00:52:43
website of some kind or something else, if it’s just00:52:46
more like00:52:48
the picture above, let’s take that we, in principle,00:52:52
check basically accepted degrees in the00:52:56
application except and here’s the functionality00:52:58
itself, what is it performs the main00:53:00
functions and what else can we check? We00:53:03
look at what the work in the application depends on,00:53:09
namely, testing00:53:12
would be suitable for a quad application, would not be00:53:15
suitable for a decent application,00:53:24
understands that this is testing,00:53:34
that another new application is important,00:53:37
cross-browser is probably important,00:53:41
no longer browse work here it is important further,00:53:45
we also have such types of00:53:47
testing as testing for00:53:49
interruption on there Albin 2, which is on00:53:53
low Internet, that is, we need to look at00:53:56
how much the Internet speed has a strong influence00:53:59
on the performance because the00:54:03
Internet companies that are accessible to them are correct00:54:06
that maybe because00:54:09
you are up to a00:54:11
remote tester, we don’t need to knock out00:54:23
exactly the hydrogen from the operating system,00:54:28
it can be for the application, it can be like00:54:32
load testing, the volume of a given00:54:35
user enters the system and starts00:54:39
using00:54:43
[music]00:54:45
then we have many types of00:54:48
performance testers, including volumetric00:54:49
testing and everything is correct there, we00:54:52
test the server separately and test00:54:55
that we have Internet speed, let’s allow00:54:58
applications to work for us if there is a bad one,00:55:00
sow from there all these that it shows,00:55:02
here the negative is connected00:55:06
cross-browser, we check here, but at the00:55:09
same time we take into account that it00:55:11
should not depend on the hardware power does not depend00:55:14
on the operating system, in fact, because it00:55:16
depends on the browser, so00:55:19
accordingly, such things should be00:55:22
kept in mind, and they may ask00:55:24
about other types, let’s say about00:55:27
native ones, and you can also, according to the00:55:30
same classification for yourself00:55:34
answer what are the features of the development of00:55:37
native types, attach what installation is already00:55:40
necessary, what depends on the operating system00:55:42
on the hardware,00:55:44
but let’s say the browser course I need00:55:48
that the browser in the native one does not work and00:55:52
if00:55:54
you want further, you can tell me what else is00:55:57
for the native one,00:56:03
but in general, I understand well, there are also hybrid ones00:56:07
also special too, how does a hybrid00:56:10
application work and00:56:12
time okay okay00:56:16
normal00:56:19
okay00:56:21
okay then let's talk about00:56:26
what let's talk about00:56:30
development methodology and about how you00:56:32
feel about the project someone gets here00:56:35
we have different methodologies there are00:56:38
some methodologies there are not00:56:50
everywhere but how once the waterfall00:56:53
model starts and since it is there everywhere there are drawings00:56:56
from top to bottom that each stage is00:56:59
gradually completed first00:57:01
second and so on and so on this is a00:57:03
return to the previous stage of the form it is00:57:07
impossible it can actually be somewhere there00:57:10
but it is very difficult to do it this is there00:57:14
at the end we get the finished product at the00:57:19
end of all the stages, so we got00:57:21
the heel, that’s how00:57:25
cool we got the product and we00:57:28
know the00:57:30
requirements, food that we always have, I,00:57:33
they developed the requirements with us, the analysis, the00:57:35
analyst did all this and00:57:38
we already have them according to them and developers00:57:40
do when development is over00:57:43
tester does from but we already all know00:57:45
what we want00:57:48
you say why did we end up there00:57:50
some kind of ajay you thought if00:57:53
buns started this is a more flexible00:57:57
methodology00:57:59
that is, of00:58:01
course there is no such clear concept of what00:58:05
we were given and all the requirements are no longer00:58:07
will be added no, and for each00:58:10
print a requirement can be added, but00:58:12
we also want this, she also wants00:58:14
this, and we launch this, as if00:58:16
flexible, and we get the output, but with00:58:20
one sprint, for example, one version00:58:23
2, the sprint is over, we add conveniently00:58:26
for 2 version so on, that is, it is already00:58:29
more flexible and00:58:31
there is no such clear concept as that00:58:35
one block has ended and another clearly begins,00:58:38
and as if the connection with the other is not00:58:40
extinguished, but the sprint ended in some00:58:45
kind of format00:58:50
[music]00:58:52
but in essence, these are the sprint and these are the same,00:58:57
that is, leading some actions in a row,00:59:01
which is accustomed to the fact that the program00:59:04
increases and improves, just ladies are00:59:07
more global00:59:10
mother or we measure at a waterfall and at00:59:13
the end of the waterfall we usually end up with a00:59:15
huge piece of program code and when00:59:18
we move with these prints00:59:20
little by little We make an increase to the program,00:59:23
well, in the end, the program also grows just00:59:25
cycles, in short, you described it correctly, you00:59:29
roasted the approach correctly, in particular, Scrum about00:59:32
this sprint and00:59:33
waterfall,00:59:35
feedback is difficult to00:59:38
better work out at each stage all00:59:41
these things there, the documentation is better written by the00:59:44
mouse, they take more time, everything else00:59:46
all this is true, but why do we need both00:59:49
then and in this case, which00:59:52
version of the development approach do we00:59:54
use?00:59:55
I think it also depends on the project,00:59:58
what kind of project we have, there is a project that01:00:01
requires everything clearly on the shelves,01:00:04
the model will fit very well,01:00:08
but this most likely there may be01:00:10
something connected there, the01:00:13
river with the mystical, not programs01:00:16
like medical ones, but if the same01:00:21
store does not require such a clear one, and01:00:24
every time we want something like this, it’s01:00:29
clear that a flexible scran will be better suited here,01:00:37
it will be here01:00:39
rather than there you further through01:00:43
we will issue01:00:45
an update for a somewhat long time, well, yes, that is, it reacts faster to01:00:49
changes in reviews, that’s why01:00:52
waterfall is also important to us how01:00:55
big the cost of an error is, because if the01:00:57
online store is bad, it’s not01:00:59
the same as if the rocket01:01:03
is good,01:01:04
right, but there is also water or besides from the crane I01:01:08
also heard flounder when01:01:12
I heard the name, yes, I still didn’t quite01:01:15
understand the differences between them and01:01:17
from the crane01:01:21
with me there01:01:23
are no sprints from the company, that is, we01:01:25
are talking about planning any based on01:01:28
each task separately and there are01:01:30
no such01:01:33
clear sprints which either something needs to01:01:35
be done or thrown out of the blog and so01:01:37
on, that is, prints and can be01:01:39
moved away,01:01:40
they are not so fixed and01:01:44
this has its pros and cons, but it’s better for01:01:47
you to read01:01:49
then01:01:51
okay okay, basically we01:01:55
discussed a lot of things,01:01:57
almost everything I wanted01:02:00
what my feedback, look, I don’t recommend01:02:04
learning any one definition01:02:07
that this is testing because I01:02:09
tried to formulate it on the fly, it did01:02:11
n’t work out very well, just learn,01:02:13
take which simple definition is the01:02:15
simplest, that is, the source of the book from01:02:18
2004 states that testing is a01:02:22
compliance check01:02:24
between the expected actual behavior of01:02:26
the program, carried out on a01:02:28
set of tests selected of course, a certain01:02:31
everything and it01:02:33
will be easier for you, you won’t have to01:02:36
try to come up with something for yourself in stress there, for01:02:42
testing purposes, too, somewhere there are01:02:46
different classifications of testing purposes,01:02:47
but we just started saying you she said01:02:49
that one of the goals is to search for bugs and01:02:51
then how difficult it became here, so01:02:53
accordingly somewhere we’ll take01:02:55
some kind of list of these goals so that01:02:59
in addition to searching for blogs there is something to01:03:01
provide feedback on the quality of the01:03:03
product01:03:05
[music] to the01:03:13
element itself like me called it well, it01:03:20
shouldn’t have been very clear, maybe you01:03:22
know, I just recommend repeating,01:03:24
let’s take a simple classification, simple01:03:27
so that you don’t have to, so that you can understand it in 101:03:31
hour and all other types of01:03:33
testing are basically normal01:03:37
about the gray box, you can read01:03:40
what you don’t and not everything interiors know01:03:42
about the sire box, too, not everyone likes to talk about it01:03:44
and discuss it, so01:03:47
appreciate it, we’re silent, we’re sinning to repeat it, why do01:03:51
we need it, I explained it, but anyway, so that I could01:03:53
fasten it for myself, so it’s good, the level of01:03:57
testing was good, the techniques were good,01:04:00
well, norma, in principle, it’s just necessary01:04:04
first of all them from a theoretical01:04:06
point of view and then give an example01:04:07
when you give an example it immediately01:04:09
seems that now I’ll01:04:11
explain with an example in the end01:04:14
everyone has such a classic01:04:17
well so the State Planning Committee has such a01:04:22
source01:04:26
829 quality standard a01:04:29
and the letter a and and three letters and English01:04:33
as in food products,01:04:36
there is such 829, it was generally01:04:41
created to describe how best01:04:43
to test in industry,01:04:46
but it is quite suitable as a source01:04:49
for01:04:51
developing software programs and there are01:04:53
things that should be there in01:04:56
terms of what01:04:58
to test, what will be tested, how01:05:01
people criteria beginning ending this is01:05:04
all just written there here is a01:05:07
checklist sketch good bug report also in01:05:11
principle everything was fine01:05:14
so it was discussed here the principles of the01:05:18
applications are a very important question from a practical01:05:21
point of view because when you01:05:24
knock on the door for a specific interview01:05:26
very now the program in the vacancy will be01:05:29
indicated We develop hybrid01:05:31
applications, or we have a native application,01:05:33
or we have web applications, and when you01:05:35
get an interview, you will already01:05:38
roughly understand what they will01:05:40
ask based on the fact that they have01:05:41
something quickly style, so you will read01:05:45
about the principles of work first queue in the01:05:48
application of native or accessible and01:05:50
hybrid and then, based on this,01:05:53
think about what types of tester you01:05:55
use for each type of application,01:05:58
