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.

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.

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.

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.

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

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.

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.

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

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

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.

UnitTest++ is a lightweight unit testing framework for C++. It was designed to do test-driven development on a wide variety of platforms. Simplicity, portability, speed, and small footprint are all very important aspects of UnitTest++. UnitTest++ is mostly standard C++ and makes minimal use of advanced library and language features, which means it should be easily portable to just about any platform.

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.

This is a Pytest plugin to randomly order tests and control Python's random.seed.

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).

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

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

This package provides relaxed test discovery for pytest.

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

CoverageTestRunner is a python module for running unit tests and failing them if the unit test module does not exercise all statements in the module it tests.

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.

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.

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.

This package provides a pytest plugin for writing tests for mypy plugins.
