These can be added later or as part of Phase 2, since core functionality is well-covered. 🚀 Next StepsOption A: Continue to Phase 2 (UpdateService tests) All 26 tests pass in CI! 🎊 |
Critical fixes identified in test review: 1. Removed 5 placeholder tests that provided false confidence - Tests were just assertTrue(true) - always passing - Replaced with honest comment about deferring to Phase 3 - See: docs/testing/test-review-critical-analysis.md 2. Fixed null intent bug in UpdateService.onStartCommand - Added defensive null check before accessing intent extras - Updated test to expect graceful handling, not NPE - Service now defaults to cleanUpdate=false when intent is null 3. Added critical rating preservation test - Test 22: testIncrementalUpdatePreservesUserRatings - Verifies annual updates don't overwrite user ratings - Most important business logic per EP-001 4. Fixed MD5 padding bug in toMD5String() - BigInteger.toString(16) doesn't pad leading zeros - Changed to byte-by-byte hex conversion with padding - Fixed in both UpdateTask and UpdateService - Added Test 7b to verify correctness and catch padding issues All tests pass.

The toMD5String helper method in the test should use final for local variables to be consistent with project coding conventions. Variables hex and b in the for-each loop should be declared as final.

The total test count "66 tests (33+18+15)" is incorrect. Based on the actual implementation, UpdateTaskTest has 28 tests and UpdateServiceTest has 10 tests (total: 38 unit tests implemented so far, not including the 15 integration tests which are not yet in this PR). Update this and other references to the total count (lines 62, 890, 897, 1117, 1293).
Created comprehensive plan for 20 integration tests needed to safely refactor UpdateService/UpdateTask (replacing AsyncTask and LocalBroadcastManager). Documents Created: 1. phase-3-implementation-plan.md (detailed, 21 tests with full code examples) 2. phase-3-quick-reference.md (TL;DR version with key patterns) Key Insights: - Current tests only call doInBackground() directly - Never test AsyncTask lifecycle (execute, callbacks, cancellation) - Never verify broadcasts are actually sent - Never test notifications in detail - TestParams bypasses real business logic Critical Missing Tests (15 MUST-HAVE): 1. AsyncTask lifecycle tests (5) - execute(), onProgressUpdate(), onPostExecute() 2. Broadcast verification tests (5) - progress, result, multiple, data correctness 3. Notification tests (5) - creation, progress, completion, cancellation, content Additional Tests (5 SHOULD-HAVE): 4. Real Params logic tests (4) - test actual updateDue()/needsUpdate() from UpdateService 5. End-to-end integration (2) - complete flow from service start to UI update Required Refactoring: - UpdateService URL injection (enable MockWebServer testing) - UpdateService Params extraction (enable real logic testing) Timeline Options: - Minimum (3-4 days): Tests 1-15 (critical only) - Full (5-7 days): All 20 tests + infrastructure Success Criteria: - Can confidently replace AsyncTask with WorkManager/Coroutines - Can confidently replace LocalBroadcastManager with LiveData/Flow - Tests catch regressions in communication layer Related: EP-001 Phase 3, safe refactoring goal 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
Day 0 refactoring to enable comprehensive integration testing. Changes: 1. Extract getBeerListUrl() as protected method - Allows tests to override with MockWebServer URLs - Enables network error testing - No behavior change - still reads from R.string.beer_list_url 2. Extract createParams() as protected method - Exposes real business logic (updateDue, needsUpdate) for testing - Tests can now verify actual AppPreferences integration - Tests can now verify actual MD5 comparison logic - Fixes TestParams bypassing real logic (critical analysis issue) Why These Changes: - Phase 3 requires testing full AsyncTask lifecycle with real network - Current implementation hardcodes URL (can't inject MockWebServer) - Current Params is anonymous inner class (can't test directly) - TestParams bypasses real logic (false confidence) Impact: - ✅ All 37 existing tests still pass - ✅ Backward compatible - no behavior changes - ✅ Enables AsyncTask lifecycle tests (Day 1-2) - ✅ Enables broadcast tests (Day 3-4) - ✅ Enables Real Params tests (Day 6) - ✅ Enables end-to-end tests with MockWebServer (Day 7) Next: Day 1-2 - AsyncTask lifecycle tests (Tests 1-5) Related: Phase 3 Week 1, safe refactoring preparation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

The toMD5String method implementation has been duplicated between UpdateTask.java and UpdateService.java. This violates the DRY (Don't Repeat Yourself) principle and creates a maintenance burden.
Recommendation: Extract this method to a shared utility class (e.g., ralcock.cbf.util.DigestUtils) to avoid duplication. Both classes can then use the single implementation.
