Regression Test Harness for the JDK: jtreg

jtreg is the test harness used by the JDK test framework. This framework is intended primarily for regression tests. It can also be used for unit tests, functional tests, and even simple product tests -- in other words, just about any type of test except a conformance test, which belong in a TCK.

As well as API tests, jtreg is designed to be well suited for running both positive and negative compiler tests, simple manual GUI tests, and (when necessary) tests written in shell script. jtreg also takes care of compiling tests as well as executing them, so there is no need to precompile any test classes.
