Check is a unit testing framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space, so Check can catch both assertion failures and code errors that cause segmentation faults or other signals. The output from unit tests can be used within source code editors and IDEs.

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

Testpath is a collection of utilities for Python code working with files and commands. It contains functions to check things on the file system, and tools for mocking system commands and recording calls to those.

This package provides a pytest plugin for generating NUnit3 test result XML output

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

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.

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

tidyall makes a lot of code tidiers and validators available from a single unified interface. You can run tidyall on a single file or on an entire project hierarchy, and configure which tidiers/validators are applied to which files. tidyall will back up files beforehand, and for efficiency will only consider files that have changed since they were last processed.

Note that if you see some missing tidier or validator modules error, you can let tidyall load them after install them. For example, one can run guix shell perl-perl-tidy perl in advance to load Perl::Tidy.

Testresources is an extension to Python's unittest to allow declarative use of resources by test cases.

doctest is a single-header testing framework for C++11 and later. It has been designed to be fast, light and unintrusive.

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.

umockdev mocks hardware devices for creating integration tests for hardware related libraries and programs. It also provides tools to record the properties and behaviour of particular devices, and to run a program or test suite under a test bed with the previously recorded devices loaded.

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.

Discover provides test discovery for unittest, a feature that has been backported from Python 2.7 for Python 2.4+.

This package is a simple helper library for writing interactive tests.

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

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.

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.

snitch aims to be a simple, cheap, non-invasive, and user-friendly testing framework. The design philosophy is to keep the testing API lean, including only what is strictly necessary to present clear messages when a test fails.

Pytest-cov produces coverage reports. It supports centralised testing and distributed testing in both load and each modes. It also supports coverage of subprocesses.

ATF, or Automated Testing Framework, is a collection of libraries to write test programs in C, C++ and POSIX shell.

The ATF libraries offer a simple API. The API is orthogonal through the various bindings, allowing developers to quickly learn how to write test programs in different languages.

ATF-based test programs offer a consistent end-user command-line interface to allow both humans and automation to run the tests.

ATF-based test programs rely on an execution engine to be run and this execution engine is not shipped with ATF. Kyua is the engine of choice.

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.

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.

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