----------------------------------------
> Consolidate State tests
> ------------------------
>
> Key: FLINK-5619
> URL: https://issues.apache.org/jira/browse/FLINK-5619
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Affects Versions: 1.3.0
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Priority: Major
> Fix For: 1.4.0, 1.3.4
>
>
> Right now, there are {{HeapListStateTest}}/{{RocksDBListStateTest}},
> {{HeapReducingStateTest}}/{{RocksDBReducingStateTest}} and
> {{HeapAggregatingStateTest}}/{{RocksDBAggregatingStateTest}}. They test the
> same thing and should be folded back into {{StateBackendTestBase}} to ensure
> that all state backends exhibit the same behaviour.
> The Heap-flavoured tests additionally check whether the state table is empty,
> this can be achieved across all state backends by introducing
> {{AbstractKeyedStateBackend.numStateEntries()}} that returns the number of
> all state entries. For the heap backend this would count the number of
> entries in the state table, for RocksDB this would get an iterator for each
> column family and count the number of entries.
> This way we have the best coverage for all state backends and ensure that
> they all behave the same.
