Behave is a tool for behavior-driven development in python. Behavior-driven development (or BDD) is an agile software development technique that encourages collaboration between developers, QA and non-technical or business participants in a software project. Behave uses tests written in a natural language style, backed up by Python code.

Aiounittest is a library that helps write tests using asynchronous code in Python (asyncio).

This Pytest plugin automatically detects and loads environment variables from a .env file before running tests.

Shows how much time was needed to run individual tests.

shUnit2 was originally developed to provide a consistent testing solution for log4sh, a shell based logging framework similar to log4j. It is designed to work in a similar manner to JUnit, PyUnit and others.

Greatest is a single-header test system for C, including macros for defining tests, grouping them into suites, and providing a test runner. It is quite unopinionated with most of its features being optional.

Python asyncio code is usually written in the form of coroutines, which makes it slightly more difficult to test using normal testing tools. pytest-asyncio provides useful fixtures and markers to make testing async code easier.

Pytest is a testing tool that provides auto-discovery of test modules and functions, detailed info on failing assert statements, modular fixtures, and many external plugins.

clitest is a portable shell script that performs automatic testing of Unix command lines.

This plugin installs a mocker fixture which is a thin-wrapper around the patching API provided by the mock package, but with the benefit of not having to worry about undoing patches at the end of a test. The mocker fixture has the same API as mock.patch, supporting the same arguments.

This package provides a Python library intended for use in automated tests. One difficulty when testing software is that the code under test might need to read or write to files in the local file system. If the file system is not set up in just the right way, it might cause a spurious error during the test. The pyfakefs library provides a solution to problems like this by mocking file system interactions. In other words, it arranges for the code under test to interact with a fake file system instead of the real file system. The code under test requires no modification to work with pyfakefs.

Mutest aims to be a small unit testing library for C projects, with an API heavily modelled on high level Behavior-Driver Development frameworks like Jasmine or Mocha.

MiniMock is a simple library for building mock objects with doctest.

Codecov collects code coverage reports from code written in Python, Java, C/C++, R, and more, and uploads it to the codecov.io service.

PyHamcrest is a framework for writing matcher objects, allowing you to declaratively define "match" rules.

PICT is a pairwise testing tool that generates test cases and test configurations. With PICT, you can generate tests that are more effective than manually generated tests and in a fraction of the time required by hands-on test case design. PICT runs as a command line tool. It takes a model file detailing the parameters of the interface as an input and generates a compact set of parameter value choices that represent the test cases you should use to get comprehensive combinatorial coverage of your parameters.

This plugin helps to use fixtures in pytest.mark.parametrize, inspied by pytest-lazy-fixture.

Pytest plugin library to test http clients without contacting the real http server.

toml-test is a language-agnostic test suite to verify the correctness of TOML parsers and writers. Tests are divided into two groups: invalid and valid. Decoders or encoders that reject invalid tests pass the tests, and decoders that accept valid tests and output precisely what is expected pass the tests. The output format is JSON.

CppUTest is a C/C++ based unit xUnit test framework. It is written in C++ but is used in C and C++ projects and frequently used in embedded systems but it works for any C/C++ project.

Catch stands for C++ Automated Test Cases in Headers and is a multi-paradigm automated test framework for C++ and Objective-C.

This Pytest plugin enables creating Pytest parametrize decorators from external files.

pytest-sugar is a plugin for py.test that changes the default look and feel of py.test, using a progress bar and showing failures and errors instantly.

Nose extends the unittest library to make testing easier.
