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.

The pytest-xdist plugin extends py.test with some unique test execution modes: parallelization, running tests in boxed subprocesses, the ability to run tests repeatedly when failed, and the ability to run tests on multiple Python interpreters or platforms. It uses rsync to copy the existing program code to a remote location, executes there, and then syncs the result back.

mbake is a Makefile formatter and linter,which is configurable via a TOML file. It intelligently deals with .PHONY declarations and line continuations, and ensures consistent formatting and style for your Makefile.

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

Pylint is a Python source code analyzer which looks for programming errors, helps enforcing a coding standard and sniffs for some code smells (as defined in Martin Fowler's Refactoring book).

Pylint has many rules enabled by default, way too much to silence them all on a minimally sized program. It's highly configurable and handle pragmas to control it from within your code. Additionally, it is possible to write plugins to add your own checks.

Theft is a library for property-based testing.

CBehave is a behavior-driven development implemented in C. It allows the specification of behaviour scenarios using a given-when-then pattern.

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

This package provides a next-generation test runner for Rust.

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

This plugin makes it simple to test general data, images, files, and numeric tables by saving expected data in a data directory (courtesy of pytest-datadir) that can be used to verify that future runs produce the same data.

Pedansee checks C source files for compliance with a particular programming style. The style is currently defined by the pedansee source code in the form of functions which walk each source file’s syntax tree. You can modify some aspects of this style through the use of regular expressions.

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

The libfaketime library allows users to modify the system time that an application "sees". It is meant to be loaded using the dynamic linker's LD_PRELOAD environment variable. The faketime command provides a simple way to achieve this.

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

Nose2 is the next generation of nicer testing for Python, based on the plugins branch of unittest2. Nose2 aims to improve on nose by providing a better plugin api, being easier for users to configure, and simplifying internal interfaces and processes.

Pytest-xprocess is an experimental py.test plugin for managing processes across test runs.

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.

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.

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.

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

Fixtures provides a way to create reusable state, useful when writing Python tests.

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

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