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.
> StreamFaultToleranceTestBase does not allow for multiple tests

> Key: FLINK-2520
> URL: https://issues.apache.org/jira/browse/FLINK-2520
> Project: Flink
> Issue Type: Improvement
> Components: Tests
> Affects Versions: 0.10
> Reporter: Stephan Ewen
> Priority: Minor
>
> 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.
