---

### 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.
