C/C++

1. C Unit Test System

CUT is a simple, to-the-point unit testing system. It's different from other unit test packages in that it follows the KISS principle. It's designed for C testing, not designed to emulate SUnit.

2. Check

Check is a unit test 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.

4. CppUnit

CppUnit is the C++ port of the famous JUnit framework for unit testing. Test output is in XML or text format for automatic testing and GUI based for supervised tests.

6. CxxTest

CxxTest is a JUnit/CppUnit/xUnit-like framework for C++. Its advantages over existing alternatives are that it doesn't require RTTI, doesn't require member template functions, doesn't require exception handling, doesn't require any external libraries (including memory management, file/console I/O, graphics libraries) and is distributed entirely as a set of header files. This makes it extremely portable and usable.
Requirement: OS Independent (Written in an interpreted language)


7. Embedded Unit

Unit testing framework for Embedded C System. Its design was copied from JUnit and CUnit and more, and then adapted somewhat for Embedded C System.

10. UnitTest

UnitTest was developed on the principle of keeping things simple as possible.To that point, the source code testing framework was made to allow the developer to easily write white/grey-box unit test cases. To make life easier, I also created a utility that generates unit test class source code. The entire project is really tiny and is designed to build and run out of the box! You should be able to get going within 5 mins. I have also provided two sample projects for you to play with in the package.
