Aryan Gupta updated HDDS-16283:
-------------------------------
Summary: Fix flakiness in trash root prepare failure test (was: Stabilize
testMoveToTrashAbortTaskWhenTrashRootPrepareFails by removing nondeterministic
success-metric assertion)
> Fix flakiness in trash root prepare failure test
> ------------------------------------------------
>
> Key: HDDS-16283
> URL: https://issues.apache.org/jira/browse/HDDS-16283
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Aryan Gupta
> Assignee: Aryan Gupta
> Priority: Major
>
> {{testMoveToTrashAbortTaskWhenTrashRootPrepareFails}} is flaky because it
> asserts that {{KeyLifecycleServiceMetrics#getNumSuccessTask()}} does not
> change. That metric is globally registered/shared, so concurrent lifecycle
> task execution in other parameterized runs can increment it, leading to
> intermittent failures (for example {{{}expected: <41> but was: <42>{}}}).
> The test has been updated to validate deterministic, local behavior instead
> of shared global metrics:
> * capture the created key,
> * inject trash-root preparation failure,
> * run {{{}LifecycleActionTask{}}},
> * assert expected failure logs are present,
> * assert the original key still exists and key count is unchanged.
