Total: ~405 tests Status: ⚠️ Proper tests but integration-heavy (Qt widgets)

3. ❌ Not Really Tests (Manual/Interactive Tests)

These are scripts that were dumped into the test directory but aren't proper automated tests:

File	Tests	Type	Issue
test_drop_bug.py	1	Manual test	References /home/dtourolle/Pictures/ - hardcoded user path!
test_async_nonblocking.py	1	Interactive GUI	Requires Qt event loop, crashes in CI
test_asset_loading.py	1	Manual test	Requires /home/dtourolle/Nextcloud/Photo Gallery/gr58/Album_pytool.ppz
test_album6_compatibility.py	1	Manual test	Requires /home/dtourolle/Nextcloud/Photo Gallery/gr58/Album6.ppz
test_version_roundtrip.py	1	Demo script	Just converted to proper test - now OK!
test_page_setup.py	1	Interactive	Requires Qt window
test_migration.py	1	Manual test	Tests migration but not fully automated
test_heal_function.py	1	Manual test	Interactive asset healing
test_zip_embedding.py	1	Demo script	Content embedding demo

Total: 9 "tests" Status: ❌ These should be:

• Moved to examples/ or scripts/ directory, OR
• Converted to proper automated tests with fixtures/mocks

4. 🔧 Test Infrastructure

File	Purpose
test_gl_widget_fixtures.py	Pytest fixtures for OpenGL testing (0 tests, just fixtures)

Problems Found

🔴 Critical Issues

1. Hardcoded absolute paths in tests:

   • test_drop_bug.py: /home/dtourolle/Pictures/some_photo.jpg
   • test_asset_loading.py: /home/dtourolle/Nextcloud/Photo Gallery/gr58/Album_pytool.ppz
   • test_album6_compatibility.py: /home/dtourolle/Nextcloud/Photo Gallery/gr58/Album6.ppz

2. Interactive tests in CI:

   • test_async_nonblocking.py - Creates Qt application and runs event loop
   • test_page_setup.py - Interactive GUI window
   • test_loading_widget.py - Interactive loading widget

3. API mismatch (FIXED):

   • ✅ test_version_roundtrip.py - Was using old load_from_zip() API
   • ✅ test_asset_loading.py - Was using old load_from_zip() API

🟡 Medium Issues

4. Tests that look like demos:
   • test_heal_function.py - Prints results but doesn't assert much
   • test_zip_embedding.py - More of a demo than a test
   • test_migration.py - Tests migration but could be more thorough

🟢 Minor Issues

5. Test file naming:
   • Some files have generic names like test_multiselect.py (2 tests)
   • Could be more descriptive

Recommendations

Short Term (Fix Immediately)

1. Mark problematic tests to skip on CI:

   @pytest.mark.skip(reason="Requires user-specific files")
   def test_album6_compatibility():
       ...
   

2. Add skip conditions for missing files:

   @pytest.mark.skipif(not os.path.exists(TEST_FILE), reason="Test file not found")
   

3. Fix the crashing test:

   • test_async_nonblocking.py needs @pytest.mark.gui or similar
   • Or mark as @pytest.mark.skip for now

Medium Term (Cleanup)

4. Move non-tests out of tests directory:

   tests/          → Keep only real automated tests
   examples/       → Move interactive demos here
   scripts/        → Move manual test scripts here
   

5. Create proper fixtures for file-based tests:

   • Use pytest.fixture to create temporary test files
   • Don't rely on user's home directory

6. Add proper test markers:

   @pytest.mark.unit      # Pure logic, no dependencies
   @pytest.mark.integration  # Needs Qt, database, etc.
   @pytest.mark.slow      # Takes >1 second
   @pytest.mark.gui       # Needs display/X server
   

Long Term (Architecture)

7. Separate test types:

   tests/unit/           # Pure unit tests (fast, no deps)
   tests/integration/    # Integration tests (Qt, mocks)
   tests/e2e/           # End-to-end tests (slow, full stack)
   

8. Add CI configuration:

   # Run fast unit tests on every commit
   # Run integration tests on PR
   # Run GUI tests manually only

Summary

Category	Count	Quality
✅ Good Unit Tests	~258	Excellent
⚠️ Integration Tests	~405	Good (but heavy)
❌ Not Real Tests	~9	Need fixing
🔧 Infrastructure	1	Good
Total	~673	Mixed

Bottom Line:

• ~66% of tests are solid (unit + integration with mocks)
• ~34% are integration tests that rely heavily on Qt
• ~1.3% are broken/manual tests that need cleanup

The test suite is generally good, but needs cleanup of the manual/interactive tests that were dumped into the tests directory.
