Adding support for your additional test frameworks is straightforward and can be done by creating a plugin that adds the appropriate code to the appropriate targets. For make-based items, you must make sure that your tests are run by the check, test, and test-only targets. You also must ensure that your check and test targets depend on all and that your test-only target does not depend on all. For Groovy-based items, you must make sure that your tests are run by the test-only target, and abuild will take care of making sure it is run by the test and check targets. For details on plugins, see Chapter 29, Enhancing Abuild with Plugins. For details on writing make rules, see Section 30.2, “Guidelines for Make Rule Authors”. For details on writing rules for the Groovy backend, see Section 30.3, “Guidelines for Groovy Target Authors”.
