Till Rohrmann commented on FLINK-2520:
--------------------------------------

+1, this will also make test infrastructure refactorings much easier since one does not have to touch every test class.

> It would be good to implement more tests into the same class (or user at least the same driver class), in order to re-use mini clusters and reducer overall test times.
> The {{StreamFaultToleranceTestBase}} does not support that.
> I think the pattern where the {{@Test}} methods are in a base class, and the actual tests only implement hook methods is not a good pattern.
> The batch API tests used this initially and we abandoned it everywhere for a more flexible implementation where the base class only sets up the. cluster/environment and the {{@Test}} methods go int the subclass.
> The {{MultipleProgramsTestBase}} is a good example of a flexible test base.
