Unit test – parameterized JUnit test without changing the runner

Is there a clean way to run parameterized JUnit 4 tests without changing the runner, that is, without using

I have unit tests and need a special runner. I can't replace this with parameterization Maybe there are some "runner chains", so I can run in two runners at the same time? (just guess...)

Solution

org. junit. runners. Parameterized by org junit. internal. builders. Annotatedbuilder is created through reflection mechanism Maybe you can extend parameterized to your own runner: @ runwith (myparameterized. Class)
