> 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.
