If you're writing Python tests, this is your reference for doing pytest properly. It covers the essentials like fixtures with different scopes, parametrization for running the same test with different inputs, and mocking external dependencies. The fixture patterns are especially useful since that's where most people either build maintainable test suites or end up with a tangled mess. You'll find examples of fixture factories, autouse fixtures, and dependency chains. Also includes test organization strategies, coverage analysis, and CI/CD integration. Good for both setting up a new test suite and refactoring an existing one that's gotten out of hand.
