From d0375aff65cd0ec9c7be6672978594ae0b9d3805 Mon Sep 17 00:00:00 2001 From: John O'Keefe Date: Wed, 25 Feb 2026 11:00:54 -0500 Subject: [PATCH] Add unit and integration tests for scan progress tracking (Step 8) Implements comprehensive test coverage for the backend scan progress tracking feature added in previous commit. Unit Tests (internal/services/worker_test.go): - TestWorker_JobResult_HasStatsFields: Verifies JobResult stores new stats fields - Tests FilesScanned, NewItems, Errors are properly stored - Confirms values are retrievable via GetJobStatus() - TestWorker_ProgressCallback_UpdatesJobResult: Verifies real-time updates - Tests progress callback mechanism updates JobResult - Confirms multiple incremental updates work correctly - Validates callback updates all stat fields Integration Tests (cmd/server/tests/scanner_integration_test.go): - TestScanProgress_TracksStatistics: End-to-end scan progress tracking - Creates library with folder via API - Triggers scan and polls status endpoint - Verifies new fields (files_scanned, new_items, errors) exist - Confirms values are non-decreasing during scan - Validates progress reaches 100% on completion - TestScanProgress_BatchingWorks: Verifies batching reduces updates - Creates library and triggers scan - Counts distinct files_scanned updates - Confirms fewer updates than files (batching working) Test Design: - Uses setupTestServer() from test_helpers.go (PROJECT_GUIDELINES.md compliant) - Single shared test setup per suite (no connection pool exhaustion) - Safe type assertions with require.True() for JSON responses - Polls for up to 30 seconds with 1-second intervals - Tests compile successfully and run in container only Coverage: - Unit tests: JobResult storage, callback updates - Integration tests: End-to-end API behavior, batching verification - All new code paths covered by tests Files modified: - internal/services/worker_test.go (added 2 tests) - cmd/server/tests/scanner_integration_test.go (new file, 254 lines) Related: TASKS-backend-progress-tracking.md Step 8 Previous commit: "Implement
