Coverage measures code coverage, typically during test execution. It uses the code analysis tools and tracing hooks provided in the Python standard library to determine which lines are executable, and which have been executed.

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.

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

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.

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

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.

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.

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.

This pytest plugin manages dependencies of tests. It allows to mark some tests as dependent from other tests. These tests will then be skipped if any of the dependencies did fail or has been skipped.

shUnit2 was originally developed to provide a consistent testing solution for log4sh, a shell based logging framework similar to log4j. It is designed to work in a similar manner to JUnit, PyUnit and others.

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.

MiniMock is a simple library for building mock objects with doctest.

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.

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

Shows how much time was needed to run individual tests.

This Pytest plugin enables creating Pytest parametrize decorators from external files.

Nose extends the unittest library to make testing easier.

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

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.

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

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

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

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.

Kyua is a testing framework for infrastructure software. Kyua is lightweight and simple, and integrates 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.
