---------------------------------
Fix Version/s: (was: 1.5.0)
1.5.1
> Create general purpose testing job
> ----------------------------------
>
> Key: FLINK-8971
> URL: https://issues.apache.org/jira/browse/FLINK-8971
> Project: Flink
> Issue Type: Task
> Components: Tests
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Priority: Critical
> Fix For: 1.5.1
>
>
> In order to write better end-to-end tests we need a general purpose testing
> job which comprises as many Flink aspects as possible. These include
> different types for records and state, user defined components, state types
> and operators.
> The job should allow to activate a certain misbehavior, such as slowing
> certain paths down or throwing exceptions to simulate failures.
> The job should come with a data generator which generates input data such
> that the job can verify it's own behavior. This includes the state as well as
> the input/output records.
> We already have the [heavily misbehaved
> job|https://github.com/rmetzger/flink-testing-jobs/blob/flink-1.4/basic-jobs/src/main/java/com/dataartisans/heavymisbehaved/HeavyMisbehavedJob.java]
> which simulates some misbehavior. There is also the [state machine
> job|https://github.com/dataArtisans/flink-testing-jobs/tree/master/streaming-state-machine]
> which can verify itself for invalid state changes which indicate data loss.
> We should incorporate their characteristics into the new general purpose job.
> Additionally, the general purpose job should contain the following aspects:
> * Job containing a sliding window aggregation
> * At least one generic Kryo type
> * At least one generic Avro type
> * At least one Avro specific record type
> * At least one input type for which we register a Kryo serializer
> * At least one input type for which we provide a user defined serializer
> * At least one state type for which we provide a user defined serializer
> * At least one state type which uses the AvroSerializer
> * Include an operator with ValueState
> * Value state changes should be verified (e.g. predictable series of values)
> * Include an operator with operator state
> * Include an operator with broadcast state
> * Broadcast state changes should be verified (e.g. predictable series of
> values)
> * Include union state
> * User defined watermark assigner
> The job should be made available in the {{flink-end-to-end-tests}} module.
> This issue is intended to serve as an umbrella issue for developing and
> extending this job.
