**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**:
```python
@pytest.mark.skip(reason="Requires user-specific files")
def test_album6_compatibility():
...
```
2. **Add skip conditions for missing files**:
```python
@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**:
```python
@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**:
```yaml
# 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.
