About pytest

pytest makes it easy to write small, readable tests with powerful fixtures, parameterization, and a rich plugin ecosystem.

Key Features

• Simple assert syntax
• Fixtures
• Parameterization
• Plugin ecosystem
• Parallel execution
• Detailed failure reports

pytest is the testing framework of choice for Python developers. Its clean syntax — just write functions that start with test_ and use plain assert statements — removes the boilerplate that unittest requires. Fixtures provide a powerful way to set up and tear down test dependencies, and parameterization lets you run the same test with multiple inputs. The plugin ecosystem extends pytest with coverage reporting, parallel execution, Django integration, and hundreds more. pytest scales from simple scripts to large applications with thousands of tests, making it suitable for every Python project regardless of size.
