What are the best practices for mocking in Python?

Best practices for mocking in Python include using the unittest.mock library, keeping mocks simple, and ensuring they are isolated.

Can you explain how to use the unittest.mock library?

Certainly! The unittest.mock library allows you to replace parts of your system under test and make assertions about how they were used.

What are some common mistakes to avoid when mocking?

Common mistakes include over-mocking, not resetting mocks between tests, and using mocks instead of real objects when not necessary.

How do I test asynchronous code with mocks?

You can use AsyncMock from unittest.mock to mock asynchronous functions, allowing you to await their results in tests.
