What are the differences between unittest and pytest for mocking?

Both unittest and pytest are popular testing frameworks in Python, but they have different approaches to mocking. unittest uses the built-in mock library, while pytest offers more flexibility with plugins like pytest-mock.

Can you give me an example of mocking in both frameworks?

Sure! In unittest, you would use unittest.mock.patch to replace a method during a test. In pytest, you can use the mocker fixture to achieve similar results.

Which one is easier to use for beginners?

Many find pytest easier due to its simpler syntax and powerful features. However, unittest is also straightforward, especially for those familiar with the standard library.

Are there any performance differences between the two?

Generally, pytest can be slower for large test suites due to its extensive features, but the difference is often negligible for smaller projects.
