Kotlin can use JUnit4 as it's test framework quite straighforwardly. Indeed this is the set up for the Kotlin tests. Moreover I can get this working for my codes. However the JUnit4 support for data-driven testing is not as good as that of TestNG. Kotlin should be able to use TestNG, but I cannot get the TestNG system to recognize the existence of the tests.
Has anyone got Kotlin working with TestNG?
