Add unit tests for PerLevelDataLoaderDispatchStrategy coverage#4308
Merged
Conversation
Cover concurrency-dependent code paths that were previously only exercised non-deterministically by integration tests, causing flaky coverage gate failures in PRs: - markLevelAsDispatchedIfReady: test the "another thread already dispatched" path (line 447) that requires two threads to race on dispatchedLevels.add() - executeObjectOnFieldValuesException: error recovery path never triggered by integration tests - executionStrategyOnFieldValuesException: same error recovery pattern at the root execution strategy level - Concurrent onCompletionFinished race: two threads completing the same level simultaneously Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
