Technology Compatibility Kit

In Java, a Technology Compatibility Kit (TCK or JCK) is a suite of tests that at least nominally checks a particular alleged implementation of a Java Specification Request (JSR) for compliance. It is one of the three required pieces for a ratified JSR in the Java Community Process, which are:

  • the JSR specification
  • the JSR reference implementation
  • the Technology Compatibility Kit (TCK)
