Example 6 with KafkaRebalanceSpec

the class KafkaRebalanceAssemblyOperatorTest method testNewWithMissingHardGoalsAndRefresh.

/**
 * Tests the transition from 'New' to 'NotReady' due to "missing hard goals" error
 * The KafkaRebalance resource is updated with "skip hard goals check" and refreshed; it then moves to the 'ProposalReady' state
 *
 * 1. A new KafkaRebalance resource is created with some specified not hard goals; it is in the New state
 * 2. The operator requests a rebalance proposal through the Cruise Control REST API
 * 3. The operator receives a "missing hard goals" error instead of a proposal
 * 4. The KafkaRebalance resource moves to the 'NotReady' state
 * 5. The rebalance is updated with the 'skip hard goals check' field to "true" and annotated with 'strimzi.io/rebalance=refresh'
 * 6. The operator requests a rebalance proposal through the Cruise Control REST API
 * 7. The rebalance proposal is ready on the first call
 * 8. The KafkaRebalance resource moves to the 'ProposalReady' state
