Example 16 with KafkaRebalanceSpecBuilder

the class KafkaRebalanceAssemblyOperatorTest method testNewToProposalReadyToRebalancingToStoppedRebalance.

/**
 * Tests the transition from 'New' to to 'ProposalReady'

 * 1. A new KafkaRebalance resource is created; it is in the 'New' state
 * 2. The operator requests a rebalance proposal through the Cruise Control REST API
 * 3. The rebalance proposal is ready on the first call
 * 4. The KafkaRebalance resource moves to the 'ProposalReady' state
 * 9. The KafkaRebalance resource is annotated with 'strimzi.io/rebalance=approve'
 * 10. The operator requests the rebalance operation through the Cruise Control REST API
 * 11. The rebalance operation is not done immediately; the operator starts polling the Cruise Control REST API
 * 12. The KafkaRebalance resource moves to the 'Rebalancing' state
 * 13. While the operator is waiting for the rebalance to be done, the KafkaRebalance resource is annotated with 'strimzi.io/rebalance=stop'
 * 14. The operator stops polling the Cruise Control REST API and requests a stop execution
 * 15. The KafkaRebalance resource moves to the 'Stopped' state
