…builds
**Optimization Benefits:**
- ✅ **Eliminated Duplicate Builds**: No longer building APKs twice in separate workflows
- ✅ **Faster CI Pipeline**: Build artifacts are reused between jobs via GitHub Actions artifacts
- ✅ **Cost Efficient**: Reduced CI compute time and GitHub Actions minutes usage
- ✅ **Single Source of Truth**: All Android Kotlin CI logic in one workflow file
**Workflow Structure:**
1. **lint** - Code quality checks with test .env file
2. **build-and-test** - Build APKs, run unit tests, upload artifacts
3. **browserstack-test** - Downloads artifacts, runs device tests (main branch only)
**Key Improvements:**
- 🏗️ APKs built once and reused via `actions/upload-artifact@v4` / `actions/download-artifact@v4`
- 🎯 BrowserStack tests only run on main branch pushes and manual triggers
- 📱 Proper artifact naming with `${{ github.run_number }}` for uniqueness
- 🔒 Secure environment variable handling without .env file creation in production jobs
- 📊 Comprehensive test reporting with BrowserStack dashboard links
**Files Changed:**
- ✅ Enhanced `android-kotlin-ci.yml` with consolidated jobs and artifact reuse
- ✅ Removed `android-kotlin-browserstack.yml` (duplicate eliminated)
- ✅ Maintained all existing functionality while optimizing resource usage
The CI pipeline now builds once, tests locally, then runs comprehensive
BrowserStack device testing with Ditto Cloud integration - all efficiently.

…ent found **Problem**: Tests were waiting unnecessary 30+ seconds even after finding documents **Root Cause**: - Fixed 20-second initial wait before even starting to check - Tests would sleep full duration even when document found immediately **Solution**: - ✅ **Immediate Check**: Start checking for document right away (no 20s delay) - ✅ **Early Exit**: Exit immediately when document is found via `return@repeat` - ✅ **Smart Retry**: Increased max attempts to 40 to accommodate sync time - ✅ **Better Logging**: Shows exactly when document is found and how long it took **Performance Impact**: - **Before**: Always waited 20s + retry time (minimum ~50s total) - **After**: Exits as soon as document syncs (could be 2-10s if document syncs quickly) - **Improvement**: 70-80% faster when documents sync quickly **BrowserStack Benefits**: - Faster test execution when Ditto Cloud sync is quick - More accurate timing measurements visible in logs - Better user experience watching test progress - Still robust with longer timeout for slow sync scenarios Tests now exit immediately when successful while maintaining reliability! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…tack verification Added visual pause after successful document sync detection to allow manual verification in BrowserStack video recordings: - ✅ Shows document on screen for 3 seconds after detection - ✅ Clear logging: "👁️ VISUAL PAUSE: Document visible for 3 seconds..." - ✅ Still exits quickly (3s pause vs previous 30s+ unnecessary wait) - ✅ Perfect for BrowserStack video review and manual verification **Timeline Now**: 1. Document found immediately → 3s pause → exit (~5-8s total) 2. Document found after sync → 3s pause → exit (~15-25s total) 3. Document not found → fail after 80s (40 attempts × 2s) This provides the perfect balance of quick execution with visual verification capability for BrowserStack testing and video review. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
**Critical Issue**: Test could pass without app launching or showing document in UI - False positives from system UI, logs, or cached text - No verification that Ditto app actually launched - Could find text in notifications, error messages, etc. **Solution**: ✅ **App Launch Verification**: First check for "Ditto Tasks" title to ensure app launched ✅ **Context Preservation**: Re-verify app context during each retry attempt ✅ **Genuine UI Testing**: Only count documents found within the actual Ditto app UI ✅ **Better Error Messages**: Clear assertions with context about what failed ✅ **Optimized Timing**: 5s app launch + 35×2s retries = 75s max (vs 80s before) **Test Flow Now**: 1. Wait 5s for app to launch 2. Verify "Ditto Tasks" title exists (proves app launched) 3. For each retry attempt: - Verify still in Ditto app context - Check for test document in task list - Exit immediately when found (after 3s visual pause) **Prevents False Positives**: - App crashes → Test fails at step 2 - System UI text → Test fails context check - Wrong app → Test fails "Ditto Tasks" verification - Cached/stale UI → Context re-verification catches it This ensures the test only passes when the document is actually visible in the running Ditto Tasks application UI, not from any other source. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
**Document Seeding Improvements:** - ✅ **Alphabetical Ordering**: Document ID now starts with "000_ci_test_" to appear first in sorted lists - ✅ **Better Format**: Changed from "github_test_android_X_Y" to "000_ci_test_X_Y" for consistent ordering - ✅ **Clear Title**: Document title "000 CI Test X_Y" is human-readable and sorts first - ✅ **Environment Variables**: Pass both DOC_ID and DOC_TITLE to BrowserStack tests **Test Logic Improvements:** - ✅ **Title-Based Comparison**: Test now looks for document by TITLE, not by parsing doc ID - ✅ **More Reliable**: Comparing visible UI text instead of internal ID fragments - ✅ **Better Logging**: Shows actual document title being searched for - ✅ **Robust Error Messages**: Include both title and ID in failure messages **Benefits:** 1. **UI Consistency**: Documents appear at top of task list (000 prefix sorts first) 2. **Test Reliability**: Comparing what users actually see (title) vs internal data (ID) 3. **Debugging**: Clear logging shows exactly what document is being searched for 4. **Visual Verification**: Easy to spot "000 CI Test" documents in BrowserStack videos **Format Examples:** - **Before**: Document "GitHub Test Task Android 12345" (ID: github_test_android_12345_67) - **After**: Document "000 CI Test 12345_67" (ID: 000_ci_test_12345_67) This ensures CI test documents are always visible at the top of the list and tests verify the actual user-visible title instead of internal IDs. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
