I was wondering if JMockit is compatible with JUnit parameterized tests or JUnitParams, because I haven't found a way to make them work together so far, since you can only specify one JUnit runner, and both JMockit, JUnitParams and Parameterized require you to use their own runner.
JMockit does not require you to use an own runner. Using an own runner is just one of the possible ways to make sure JMockit got initialized properly before your tests run. You can also add JMockit as Java agent via commandline parameters, depend on classpath ordering (having JMockit in the classpath before JUnit) or call the JMockit initialization method manually before the actual tests start if you have such a place where you can call it, e.g. if you use an own JUnit runner.
