What are the differences between pytest and unittest?

Both pytest and unittest are popular testing frameworks in Python. unittest is built into Python's standard library, while pytest is a third-party library that offers more features and flexibility.

Can you explain some specific features of pytest?

Sure! Pytest supports fixtures, parameterized testing, and has a rich plugin architecture. It also provides better output formatting and easier test discovery.

Is it easy to migrate from unittest to pytest?

Yes, migrating from unittest to pytest is generally straightforward. You can run unittest tests with pytest, and gradually refactor your tests to take advantage of pytest's features.

Which one do you recommend for new projects?

For new projects, I recommend using pytest due to its simplicity and powerful features. However, if you're working in an environment where unittest is already established, it might be better to stick with it.
