pytest

Automate Python testing by writing functions named test_* and running pytest to execute them. It eliminates boilerplate by providing fixtures for setup and teardown, plus parametrization to run a single test against multiple inputs.

Yes, pytest works with Django and Flask through its rich plugin ecosystem. It supports web application testing by allowing you to apply fixtures and parametrization directly to your Django or Flask projects.

The best way to run multiple inputs is using parametrization in pytest. This feature allows you to define a list of inputs and expected outcomes, automatically generating distinct test cases for each parameter combination.

Yes, you can execute tests in parallel and configure reporting via CLI. pytest supports parallel execution through its plugin ecosystem and allows configurable reporting directly through command line interfaces and configuration files.

Fixture management handles setup and teardown by injecting reusable resources into your test functions. pytest fixtures manage state initialization and cleanup, ensuring a reliable environment without repeating tedious boilerplate code across tests.

You need plugins from the pytest ecosystem to enable async testing. The core framework supports test discovery and configuration, but asynchronous test execution relies on integrating specific plugins designed for async validation.
