[@vikrantmahajan142]

It's an amazing video! You have really broken the concepts into very easily understandable components. Loved your way of explanation! Thanks

That's just what i needed right now. Oleg, thank you!
Been watching your channel since 2017, some time supported on patreon, your content never disappoints. You make very clear and understandable explanation on every important nuance, incrementally from easy to advanced stuff. Sometimes I miss, when there are no new videos for a long time :) Big thank you anyway. I personally think that you made a huge, or even biggest contribution(not size, but in terms of quality, for sure) into instructional videos for Russian self-taught python developers, and now for International community. Time ago your videos helped me to learn a lot of things, to get a first paid developer job and etc.
Legend!

You're a saviour man. I had issues with DI and mocks but this video has simplified everything for me. Great explanation!👏

[@roberto_camp]

Fantastic tutorial. Took me from almost no knowlege of python unittest and mocks to very confident. Thank you!

[@RedEyedCoderClub]

Thank you very much!

[@JedLearns]

Really great tutorial! From having little to no idea about how Python Mocks works to now having a good understanding. Time to improve my understanding now through practice, thank you!

[@diwakardayalan]

No one in TH-cam was able to explain this mock with such a simple example. If I could request would you be able to make a series on testing AWS services using mock.

[@TheSirgo23]

This video is just awesome. I was stuck reading docs and couldn't apply it in my test cases. Thanks a lot for this great explanation.

[@AVISH747]

Excellent. I was breaking my head on mock and patch.. now its crystal clear.

THATS what happened to your previous channel. Such a great surprise to occasionally find out that you are not done with youtube.
Since me watching my first video on your channel many things happened, and even after all those years i can definitely say that your material is way beyond the others in terms of quality.
Keep it up man

[@RedEyedCoderClub]

Thank you very much!

Thanks for the explanation. The mock is very powerful. I feel conformable starting to use it now

this is great video, with this one video i wrote my 1st unit test case of my project. Thanks

hi, i have seen many and many tutos python mocks, but this one is simple, clear and understable. 👍 and many thanks !

[@RedEyedCoderClub]

Thank you very much!

[@aashrayzaveri9510]

Great explanation. Was struggling with the concept. Now I am confident with the topic

[@williamgillett1756]

Excellent video - great examples - so simple, but complete, I agree with others that your commentary is incredible. You describe what is going on at every step - both in the code and in the underlying logic. Mocks can be confusing to me and you really help break down the concepts so thoroughly. This is my first experience watching videos by you. I will be back for more! PS - I usually use pytest, but it was helpful to see the more traditional unittest methodology applied to mocks. Translating your code to pytest was a good exercise for a newbie like me.

[@aamirsuleman9815]

Amazing work! Never thought of pronouncing OK as Awk.

[@bennguyen1313]

So the patch decorator is possible only because of the unittest import?
Can unittest / mock be used to automate testing of any software or only python?
Would love to learn to use tools to write more disciplined code! For example, most tools are pricey as their meant for large enterprises, but there seems to be a few open-source / free options..
Requirement Management - rmtoo florath , doorstop-dev / doorstop
Static Structural Source Code Analysis (SAST) - clang-tidy , cppcheck
Configuration Management / Storage and Version Control System (VCS) - Git, Mercurial, MS TFS, Subversion
Continuous Integration (build and test) / Continuous Delivery-Deployment - Jenkins, GitLab CI/CD

[@RedEyedCoderClub]

Isn't it too basic for you?

[@zakchips]

@@RedEyedCoderClub But it was only introduction. And may be you'll find some time to continue this topic comparing different approaches in mocking. what are advantages if present in module requests_mocking (or responses) comparing with unittest.mock patch. Or creating custom exceptions working with raise_for_status (had some troubles testing them at my work). Thank you very much.

[@RedEyedCoderClub]

Yep, that's right. I knew that it's too basic for you, and planned to make more.

[@subrinalazad3215]

Thanks for the video.
I'm facing a error when running the test.py
ModuleNotFoundError: No module named 'main'

[@RedEyedCoderClub]

Ok, have you the `main.py` module?
What's you directory/files structure?
Did you check your code twice?

[@Mehdi-hw6yi]

Thank you for the video, very clear but how can you mock multiple elements in one function? For example if a function calls two functions.

[@RedEyedCoderClub]

It's a good question!
First of all you can use more then one @patch decorator
@patch('main.one_func')
@patch('main.two_func')
def test_function():
pass
Also you can use patch as a context manager. Smth like this:
with patch('main.one_func') as mock_one_func:
pass
Also you can use patch() inline. Smth like this:
mock_one_func = patch('main.one_func').start()
...
mock_one_func.stop()
It's all about the scope.

[@Mehdi-hw6yi]

@@RedEyedCoderClub Thank you, I have tried the first two solutions and they work well. Not sure how to use the last one though.

[@RedEyedCoderClub]

It's great!

[@जैराधाकृष्ण]

Many Thanks. Can we get code written?

[@RedEyedCoderClub]

Sorry, no. It's just an example

[@maronthehill]

2:10 How is the test_add() method called?

[@Jeremiah_]

The unittest module uses the naming convention of the function to execute the test. So let’s say you just remove the ‘test’ from test_add it wouldn’t be able to execute the function. To wrap up the explanation, the unittest module requires strict naming convention in order for it to execute a particular unit or suite of multiple isolations.

Спасибо)) Только в работе как раз необходимость возникла в тестирование углубиться, а тут такой подгон. Спасибо Олег, во многом и благодаря вашим роликам сменил профессию с тренера по футболу, на пайтон разработчика!)

[@RedEyedCoderClub]

Вау, это круто! Не поделитесь ли историей перехода?

[@alexdzehil7194]

@@RedEyedCoderClub если коротко то можно глянуть на ютубе "Moscow Python Podcast из преподавателя в разработчики". Если чуть длиннее, то переход занял у меня ровно год активного изучения питона. Начал с бесплатных курсов на степике, там же курс по линуксу, затем книги и в том числе делал блоги на джанго и фласке по вашим обучающим видео с русскоязычного канала. Затем платные курсы от создателей подкаста в который меня потом и пригласили. Скажу что то что прошел ваш курс и сделал блог на джанго мне очень пригодилось при прохождении платных курсов. Там суть в том что короткая вводная часть и затем проект на фласке или джанго, я выбрал джанго и чувствовал себя поувереннее своих сокурсников, успешно защитил проект и устроился на работу. Компания у нас небольшая да и в современных реалиях от разработчика при постановке задачи также требуется грамотная систем логирования и тестирование. Вот сейчас углубляюсь в тестирование и логирование также по вашим роликам, так как на курсах этому уделяется очень мало времени.

[@RedEyedCoderClub]

@@alexdzehil7194 Спасибо большое за ответ. Я вас от всей души поздравляю и желаю вам успехов! Действительно очень здорово, что вы вот так взяли и переключились. Это очень тяжело. Не каждый так может, а вы смогли. Просто прекрасно!
