This video is the third part of Python testing using Mocks series (or just Python Mocks). In this video we'll touch the mocking of functions that use Python Requests library with Responses library.
How to use Python Responses library to mock function, raise_for_status, exceptions.
In this Python testing tutorial as an example I use a function that makes a request to external API. And as a testing library I use unittest.
It's a Python unittest mock tutorial for beginners.

Timecodes:
00:00 - Beginning.
01:31 - Writing a test for a function that should return value if JSON object with a certain structure is provided
05:50 - Testing the raise_for_status() function with Python Responses library.
06:49 - Testing a logic when Exception is raised
Why Python mocks are important:
- Mocks eliminate dependency on network, database calls, calls to OS (it will speed testing)
- we get isolated unit tests,
- we can test methods that have no return value
- reduce test complexity. We don't have to write complex logic to handle behavior of methods under tests.
- don't have to wait to implement other methods.
When should you mock?
When you don't want to actually call an object

Thank you! Responses package is so much easier to test requests package. It was very easy to test urllib3 Retry mechanism.

Just few suggestions: 1. short video about custom exceptions (requests_mock) with raise customException flow instead of return 2. Type hits 3. creation of custom of django templates with custom views/mixins in django admin. Thank you.

My comment should be probably deleted by YT bot, but I can write it again: my suggesstion is 1. how we can test a third-party application for Django with pytest and tox. 2. debug django app with pdb Thank you very much.

thanks mate ! more on mocking as your videos are quite promising just a suggestion on request_mock module 👍

@RedEyedCoderClub 2 жыл бұрын

Thank you, and thanks for your suggestion. By the way, why request_mock? The Responses library seems to me to be more convenient, and it has better support.

Thank You for tutorial. Can we use mocks with pytest? Maybe You can make few series about pytest fixtures, parametrization etc? anyway thanks, nice job.

Of course we can use all these tools with pytest too. Thanks for your suggestions, I'll make videos with pytest.
