A bnd tester using JUnit Platform. Like biz.aQute.tester, this bundle will add itself to the -runbundles at the end. At startup, this bundle will then look for TestEngine implementations among the loaded bundles and use them to execute the tests. This bundle does NOT contain the necessary TestEngine implementations for JUnit 3, 4 or 5 - it will import them just like any other bundle.

There is a newer version: 7.0.0
