This package provides a pytest plugin to check import ordering using isort.

Pytest uses one of four different spellings of parametrize. This plugin allows you to use all four.

This is a Python library for test combinations generator. The generator allows one to create a set of tests using pairwise combinations method, reducing a number of combinations of variables into a lesser set that covers most situations.

This package provides a plugin for Pytest which adds the ability to retry flaky tests, thereby improving the consistency of the test suite results.

This package provides a Pytest extension for sharding tests at the granularity of individual test cases, which can be run in parallel and on multiple machines.

This package provides a virtualenv fixture for the py.test framework.

This package provides a pytest plugin to re-run tests to eliminate flaky failures.

re-assert provides a helper class to make assertions of regexes simpler.

This package provides a Pytest plugin for customizing string representations of doctest results. It can change the display hook used by doctest to render the object representations.

This package provides a plugin for testing Cython extension modules.

This package provides a plugin for the pytest framework that allows developers to detect whether any file handles or other file-like objects were inadvertently left open at the end of a unit test.

This Pytest plugin provides unittest subTest() support and subtests fixture.

Validation library and CLI tool for checking on pyproject.toml files using JSON Schema.

This is a py.test plugin to facilitate the generation and comparison of data arrays produced during tests, in particular in cases where the arrays are too large to conveniently hard-code them in the tests.

This plugin makes it simple to test general data, images, files, and numeric tables by saving expected data in a data directory (courtesy of pytest-datadir) that can be used to verify that future runs produce the same data.

pytest-random-order is a Pytest plugin that randomizes the order of tests. This can be useful to detect a test that passes just because it happens to run after an unrelated test that leaves the system in a favourable state. The plugin allows user to control the level of randomness they want to introduce and to disable reordering on subsets of tests. Tests can be rerun in a specific order by passing a seed value reported in a previous test run.

Pytest plugin providing a fixture interface for freezegun.

This plugin defines Pytest markers to ensure that some tests, or groups of tests run in a specific order.

pytest-qt is a Pytest plugin that allows programmers to write tests for PyQt5 and PySide2 applications.

The main usage is to use the qtbot fixture, responsible for handling qApp creation as needed and provides methods to simulate user interaction, like key presses and mouse clicks.

Beartype aims to be a very fast runtime type checking tool written in pure Python.

flexmock is a testing library for Python that makes it easy to create mocks, stubs and fakes.

Blockbuster is a Python package designed to detect and prevent blocking calls within an asynchronous event loop. It is particularly useful when executing tests to ensure that your asynchronous code does not inadvertently call blocking operations, which can lead to performance bottlenecks and unpredictable behavior.

It does this by wrapping common blocking functions and raising an exception when they are called within an asynchronous context. Note that Blockbuster currently only detects asyncio event loops and is tested only with CPython.

This pytest plugin provides fixtures to simplify Flask app testing.

Pyflakes statically checks Python source code for common errors.
