> Key: FLINK-8238
> URL: https://issues.apache.org/jira/browse/FLINK-8238
> Project: Flink
> Issue Type: Improvement
> Components: Streaming, Tests
> Affects Versions: 1.5.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Fix For: 1.5.0
>
>
> The {{StreamTaskTestHarness}} offers 2 methods for settting up an
> {{OperatorChain}}:
> * setupOutputForSingletonOperatorChain
> * setupOperatorChain
> We should add a check to make sure that only one of these methods is called.
> Calling both methods leads to undefined behavior by the task and is a bit
> tricky to debug.
