Parameterized jUnit test without changing runner

Is there a clean way to run parameterized jUnit 4 tests without changing the runner, i.e. without using @RunWith(Parameterized.class)?

I have unit tests which require a special runner already and I can't replace this one with Parameterized. Maybe there is some kind of "runner chaining" so I could both runners at the same time? (Just a wild guess...)

Solution

  • org.junit.runners.Parameterized is created by org.junit.internal.builders.AnnotatedBuilder by reflect mechanism. Maybe you could extend Parameterized as your own Runner: @RunWith(MyParameterized.class).
