-----------------------------------

             Summary: 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.
