In their own words
CppUTest
CppUTest is a free C/C++ xUnit framework for unit testing and test-driven development, frequently used in embedded systems. It organizes tests into groups with setup and teardown, and provides assertions for conditions, comparisons, strings, numbers, pointers and memory. CppUMock supplies mocking support, and the manual describes optional Google Mock integration. C source files can use CppUTest macros and wrappers to register tests with the framework. Its per-test memory leak check compares memory use before setup with usage after teardown. Plugins cover memory leak detection, pointer restoration and floating-point exception flags. The command-line runner can emit JUnit-style XML and TeamCity XML for CI systems; the manual also describes running Google Tests alongside CppUTest tests in one binary. Build options include source builds using CMake or autoconf, Debian and Ubuntu packages, and Homebrew on macOS. It supports Linux, macOS, Windows and self-hosted use, and the repository identifies its license as BSD-3-Clause. One build limitation is that MakefileWorker.mk is available for source builds but is not supported by pre-packaged installs.
FsCheck
FsCheck checks properties of.NET programs against randomly generated cases. Developers can express properties in F#, C# or VB, then run them with the built-in runner from an interactive session, a command-line program or a test framework. Integrations are documented for xUnit.net and NUnit, with user-created integrations for Expecto, Fuchu, AutoFixture and MSTest. When a property fails, FsCheck shrinks the input and shows a minimal counterexample. Developers can also define custom generators and shrinkers and group them in Arbitrary instances. The library supports parameterized cases and parallel execution, and its packages and NUnit and xUnit.NET plugins are available from NuGet. FsCheck is free: its listed plan is free, with a BSD license permitting commercial and non-commercial modification and redistribution. It runs on Linux, macOS and Windows. The project maintains version 3.x, but its documentation covers 2.x and is described as out of date and incomplete. Its model-based testing API is experimental and exempt from semantic-versioning guarantees.
