Software Unit Tests (Language Independent Approach)
Automation of Unit and System Tests. Tests can be implemented in any language and on many platforms. The flexible approach enables the inclusion of many types of tests, such as memory leak checks (using valgrind), coding rule checks, complexity checks, etc. Tests are run by a simple call to hwut in a base directory of a project. In particular for C, HWUT supports make file generation using 'sos' and 'sols' modes. Remote control-able function stubs may be generated using the 'stub' mode. Test cases can be generated using the 'gen' mode, and state machine walkers by the 'sm_walker' mode. Over the last decade HWUT has matured towards a full fledged unit test tool for a wide variety of applications.
Tikal's open source Application Development & Deployment is comprised of fully integrated suites that cover the entire software life-cycle, include tools for development and deployment of applications, software configuration management and ASQA.
Analysis tools for scale test data generated by The Grinder.
CUBRID QA project contains a test-automation tool and many kinds of test cases for CUBRID database.
ETICS stands for "eInfrastructure for Testing, Integration and Configuration of Software". It provides software professionals with an "out-of-the-box" build and test system, powered with a build and test product repository.
Fressia Project is an effort to develop an Open Source general framework for Testing Automation. It's intended for users (testers) that want a simple tool which can be used just out of the box. It's does not requires any complicated configuration stuff
Sadly JFCUnit is no longer supported but idea is neat and with a few more improvements it can be even more useful tool for regression testing. JFCUnit-2 will have distributed testing, SWT support, JUnit independent and lots of other improvements.

STDL (Structured test description language) is a domain-specific testing language that is used to auto-generate unit test code. It supports a myriad of output languages (incl. C#). The project's aim is that of reducing the resources required for testing
