Review comment:
Can you try to convert this class to public non inner class? This class can
definitely evolve into something that's re-used across multiple tests, since
this is not the only place that's using `mock(StreamTask.class)`.
I think it's easy to do with "refactor" options in Intellij:
1. refactor -> convert to static class (to generate a constructor for
passing all of the fields)
2. refactor -> move (to move from inner class to outer level)
I guess the only "problematic" thing to solve is
`streamTaskStateInitializer` field, which is non final.
