pytest is a popular tool for testing Python code. It helps you check that your programs work as expected. With pytest, you can write simple tests using plain assert statements. The framework handles test discovery and gives clear failure reports.
pytest has a powerful fixture system. Fixtures let you set up data or objects that your tests need. You can also run the same test with different inputs using parametrization. This saves time and makes tests more thorough.
pytest works well with many Python web frameworks. You can test FastAPI, Django, and Flask applications easily. It also supports async code, mocking, and code coverage. Hundreds of plugins extend its capabilities.
