Replace Thread.sleep() with proper synchronization in tests#1773
Merged
Conversation
Tests were using Thread.sleep() (up to 5 seconds each) to wait for async operations like resource downloads and validation triggers, making the test suite unnecessarily slow (~71s test time). Key changes: - BaseFileTempTest: replace sleep(1050) with Files.setLastModifiedTime() to ensure filesystem change detection without waiting - XMLLanguageService: return download futures from publishDiagnostics() so tests can await them directly - XMLAssert: add awaitDownloads() helper, remove retrigger callback - MockXMLLanguageClient: add waitForDiagnosticCount() polling helper - Replace all 5-second HACK sleeps with awaitDownloads() - Replace async validation sleeps with waitForDiagnosticCount() - DocumentLifecycleParticipantTest: poll for lifecycle callback completion - CacheResourcesManagerTest: reduce cache TTL from 1s to 100ms Build time reduced from ~1m17s to ~15s (5x faster).
