Google Test features an XUnit test framework, automated test discovery, death tests, assertions, parameterized tests and XML test report generation.

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

KLEE is a symbolic virtual machine built on top of the LLVM compiler infrastructure.

Mock is a library for testing in Python. It allows you to replace parts of your system under test with mock objects and make assertions about how they have been used. This library is now part of Python (since Python 3.3), available via the unittest.mock module.

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 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.

This package provides a pytest plugin to test that mypy produces a given output. As mypy can be told to display the type of an expression this allows you to check mypys type interference.

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

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.

CppUnit is the C++ port of the famous JUnit framework for unit testing. Test output is in XML for automatic testing and GUI based for supervised tests.

This package provides a py.test plugin supplying fixtures and markers to simplify testing of asynchronous tornado applications.

This package provides a Pytest plugin which enables running each test in a subprocess and will report if a test crashed the process. It can be useful to isolate tests against undesirable global environment side-effects (such as setting environment variables).

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.

pytest-mypi is a static type checker plugin for Pytest that runs the mypy static type checker on your source files as part of a Pytest test execution.

Flaky is a plugin for nose or py.test that automatically reruns flaky tests.

Ideally, tests reliably pass or fail, but sometimes test fixtures must rely on components that aren't 100% reliable. With flaky, instead of removing those tests or marking them to @skip, they can be automatically retried.

Testrepository provides a database of test results which can be used as part of a developer's workflow to check things such as what tests have failed since the last commit or what tests are currently failing.

checkmake is an experimental tool for linting and checking Makefiles. It allows for a set of configurable rules being run against a Makefile or a set of *.mk files.

Cppcheck is a static code analyzer for C and C++. Unlike C/C++ compilers and many other analysis tools it does not detect syntax errors in the code. Cppcheck primarily detects the types of bugs that the compilers normally do not detect. The goal is to detect only real errors in the code (i.e. have zero false positives).

FreezeGun is a library that allows your python tests to travel through time by mocking the datetime module.

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.

The googlebenchmark C++ library support the benchmarking of functions, similar to unit tests.

Testscenarios provides clean dependency injection for Python unittest style tests.

This package provides testing utility modules for testing JSON APIs with Behave.
