Although jtreg was originally designed to execute Technology Compatibility Kit (TCK) compliance tests, it is not designed to check compliance of a particular Java implementation to the specification, but to test any regressions suite for the Java platform.^[2]

History

jtreg started in 1997, during JDK 1.2 development.^[3] Being developed prior to JUnit existence, jtreg was initially not compatible with JUnit's test syntax,^[2] but later versions added a limited compatibility with JUnit.^[4]

Use in OpenJDK

OpenJDK, the open-source implementation of the Java programming language^[5] encourages the use of jtreg tests for patch submissions.^[6]
