> This change added a new test class called TestReplicationManagerScenarios. It
> work via test definitions in JSON, such as:
> {code}
> { "description": "Perfect Replication Ratis", "containerState": "CLOSED",
> "replicationConfig": "RATIS:THREE", "sequenceId": 12,
> "replicas": [
> { "state": "CLOSED", "index": 0, "datanode": "d1", "sequenceId": 0,
> "isEmpty": false, "origin": "o1"},
> { "state": "CLOSED", "index": 0, "datanode": "d2", "sequenceId": 0,
> "isEmpty": false, "origin": "o2"},
> { "state": "CLOSED", "index": 0, "datanode": "d3", "sequenceId": 0,
> "isEmpty": false, "origin": "o3"}
> ],
> "expectation": {},
> "commands": []
> }
> {code}
> Which defines the container state and the replica states, along with expected
> commands and outputs from processing the container.
> For each scenario, it runs through the Replication Manager check phase,
> re-runs the check-phase in read only mode and also runs the processing phase,
> where RM will send commands to fix the problems.
> There are also some tests added to prove the framework is working, but
> further Jira's would allow us to expand the test scenarios and remove many
> similar unit tests that are harder to understand.
