The JavaTest harness is a set of tools designed to execute test programs. It was originally designed to execute tests in the JavaTM 2 SE Technology Compatibility Kit (TCK) (formerly the Java Compatibility Kit (JCK)). Among other things, the harness has evolved the ability to execute non-JCK testsuites. The JDK regression test suite is one such suite.
An open source version of the harness is available at
