/*
|
|
Basic Tests:
|
|
√ Place when there is nothing in the cluster
|
|
√ Place remainder when there is some in the cluster
|
|
√ Scale down from n to n-m where n != m
|
|
√ Scale down from n to zero
|
|
√ Inplace upgrade test
|
|
√ Inplace upgrade and scale up test
|
|
√ Inplace upgrade and scale down test
|
|
√ Destructive upgrade
|
|
√ Destructive upgrade and scale up test
|
|
√ Destructive upgrade and scale down test
|
|
√ Handle lost nodes
|
|
√ Handle lost nodes and scale up
|
|
√ Handle lost nodes and scale down
|
|
√ Handle draining nodes
|
|
√ Handle draining nodes and scale up
|
|
√ Handle draining nodes and scale down
|
|
√ Handle task group being removed
|
|
√ Handle job being stopped both as .Stopped and nil
|
|
√ Place more that one group
|
|
|
|
Update stanza Tests:
|
|
√ Stopped job cancels any active deployment
|
|
√ Stopped job doesn't cancel terminal deployment
|
|
√ JobIndex change cancels any active deployment
|
|
√ JobIndex change doens't cancels any terminal deployment
|
|
√ Destructive changes create deployment and get rolled out via max_parallelism
|
|
√ Don't create a deployment if there are no changes
|
|
√ Deployment created by all inplace updates
|
|
√ Paused or failed deployment doesn't create any more canaries
|
|
√ Paused or failed deployment doesn't do any placements
|
|
√ Paused or failed deployment doesn't do destructive updates
|
|
√ Paused does do migrations
|
|
√ Failed deployment doesn't do migrations
|
|
√ Canary that is on a draining node
|
|
√ Canary that is on a lost node
|
|
√ Stop old canaries
|
|
√ Create new canaries on job change
|
|
√ Create new canaries on job change while scaling up
|
|
√ Create new canaries on job change while scaling down
|
|
√ Fill canaries if partial placement
|
|
√ Promote canaries unblocks max_parallel
|
|
√ Promote canaries when canaries == count
|
|
√ Only place as many as are healthy in deployment
|
|
√ Limit calculation accounts for healthy allocs on migrating/lost nodes
|
|
√ Failed deployment should not place anything
|
|
√ Run after canaries have been promoted, new allocs have been rolled out and there is no deployment
|
|
√ Failed deployment cancels non-promoted task groups
|
|
√ Failed deployment and updated job works
|
|
√ Finished deployment gets marked as complete
|
|
√ The stagger is correctly calculated when it is applied across multiple task groups.
|
|
√ Change job change while scaling up
