Cmocka is a unit testing framework for C with support for mock objects. It only requires the standard C library, and works with different compilers. Cmocka supports several different message output formats like Test Anything Protocol, Subunit, xUnit XML or the original cmockery output format.

Theft is a library for property-based testing.

Catch2 stands for C++ Automated Test Cases in Headers and is a multi-paradigm automated test framework for C++ and Objective-C.

Kyua is a lightweight and simple testing framework for infrastructure software., integrating well with various build systems and continuous integration frameworks.

Kyua features an expressive test suite definition language, a safe runtime engine for test suites and a powerful report generation engine.

Kyua is able to execute test programs written with a plethora of testing libraries and languages. The library of choice is atf, for which Kyua was originally designed, but simple, framework-less and TAP compliant programs can also be executed through Kyua.

Trompeloeil is a thread-safe header-only mocking framework for C++11/14.

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

CxxTest is a unit testing framework for C++ that is similar in spirit to JUnit, CppUnit, and xUnit. CxxTest does not require precompiling a CxxTest testing library, it employs no advanced features of C++ (e.g. RTTI) and it supports a very flexible form of test discovery.

Pytest-examples provides functionality for testing Python code examples in docstrings and markdown files, with its main features being:

• lint code examples using ruff and black

• run code examples

• run code examples and check print statements are inlined correctly in the code

• It can also update code examples in place to format them and insert or update print statements

CUnit is a lightweight system for writing, administering, and running unit tests in C. It provides C programmers with basic testing functionality with a flexible variety of user interfaces.

Subunit is a streaming protocol for test results. Subunit comes with command line filters to process a subunit stream and language bindings for Python, C, C++ and shell. Bindings are easy to write for other languages.

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

Testscenarios provides clean dependency injection for Python unittest style tests.

Catch2 stands for C++ Automated Test Cases in Headers and is a multi-paradigm automated test framework for C++ and Objective-C.

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.

Python-subunit is a Python implementation of the subunit test streaming protocol.

This package provides a go test runner with output optimized for humans, JUnit XML for CI integration, and a summary of the test results.

Parameterized is a Python library that aims to fix parameterized testing for every Python test framework. It supports nose, py.test, and unittest.

Scripttest is a Python helper library for testing interactive command-line applications. With it you can run a script in a subprocess and see the output as well as any file modifications.

This software is a set of testing tools for GNU Guile projects with SRFI 64-based test suites. It comes with a command-line interface to run test collections, and a library that includes a test runner and helpers for writing tests.

Rapidcheck is a property based testing framework for C++. It works by generating random data to try and find a case breaks your given pre-condition.

Testtools extends the Python standard library unit testing framework to provide matchers, more debugging information, and cross-Python compatibility.

Hypothesis is a library for testing your Python code against a much larger range of examples than you would ever want to write by hand. It’s based on the Haskell library, Quickcheck, and is designed to integrate seamlessly into your existing Python unit testing work flow.

µnit is a small testing framework for C with nested test suites, parameterized tests, timing of the wall clock and CPU time, reproducible random number generation, and more.

TestU01 is a software library, implemented in the ANSI C language, and offering a collection of utilities for the empirical statistical testing of uniform random number generators.
