## Changes Made
|
||||
|
||||
### 1. Enhanced `tests/test_encryption.py`
|
||||
|
||||
Added 2 new test cases to cover error handling scenarios:
|
||||
|
||||
#### Test: `test_get_cipher_suite_import_error`
|
||||
- **Purpose**: Test behavior when cryptography library is not installed
|
||||
- **Coverage**: Lines 50-56 (ImportError exception block)
|
||||
- **Approach**: Mock builtins.__import__ to raise ImportError for cryptography
|
||||
|
||||
#### Test: `test_get_cipher_suite_general_exception`
|
||||
- **Purpose**: Test behavior when cipher initialization fails with general exception
|
||||
- **Coverage**: Lines 57-59 (Exception exception block)
|
||||
- **Approach**: Mock hashlib.sha256 to raise RuntimeError
|
||||
|
||||
### 2. Created `tests/test_main.py` (New File)
|
||||
|
||||

|
||||
- **`app/api/url_upload.py`**: Increased from **80.22%** to **91.21%** ✅
|
||||
- **`app/views/files.py`**: Increased from **18.45%** to **90.61%** ✅
|
||||
|
||||
## Coverage Details
|
||||
|
||||
### app/utils/encryption.py - 100% Coverage
|
||||
### app/api/url_upload.py (91.21% coverage)
|
||||
|
||||
**Previously uncovered lines (50-59)**: Now fully covered
|
||||
- Lines 50-56: ImportError exception handling
|
||||
- Lines 57-59: General Exception handling
|
||||
**Previous Coverage**: 80.22% (138 statements, 20 missing, 44 branches, 12 partial)
|
||||
**New Coverage**: 91.21% (138 statements, 6 missing, 44 branches, 10 partial)
|
||||
|
||||
**Test approach**:
|
||||
- Mocked imports to simulate cryptography library unavailability
|
||||
- Mocked internal functions to trigger exception paths
|
||||
- Verified correct fallback behavior (returning None, logging warnings/errors)
|
||||
#### New Tests Added (10 tests):
|
||||
1. `test_process_url_request_exception` - Tests handling of generic RequestException
|
||||
2. `test_process_url_oserror_during_save` - Tests OSError when saving file to disk
|
||||
3. `test_process_url_unexpected_exception` - Tests handling of unexpected exceptions
|
||||
4. `test_process_url_filename_without_extension` - Tests files without extensions
|
||||
5. `test_process_url_empty_path_uses_download` - Tests default filename for URLs without path
|
||||
6. `test_validate_url_no_hostname` - Tests URL validation without hostname
|
||||
7. `test_validate_file_type_by_extension_fallback` - Tests file type validation by extension
|
||||
8. `test_is_private_ip_ipv6_loopback` - Tests IPv6 loopback detection
|
||||
9. `test_is_private_ip_link_local` - Tests link-local address detection
|
||||
10. `test_process_url_sanitizes_dangerous_filename` - Tests filename sanitization security
|
||||
|
||||
### app/main.py - 91.75% Coverage
|
||||
#### Coverage Improvements:
|
||||
- **Error handling**: Now covers all exception handlers (RequestException, OSError, unexpected exceptions)
|
||||
- **Edge cases**: Covers missing hostnames, empty paths, files without extensions
|
||||
- **Security**: IPv6 loopback, link-local addresses, dangerous filename sanitization
|
||||
- **File validation**: Extension-based fallback validation
|
||||
|
||||
**Previously uncovered lines**: 38 lines
|
||||
**Now covered**: 34 lines (4 remaining uncovered)
|
||||
### app/views/files.py (90.61% coverage)
|
||||
|
||||
**Remaining uncovered lines**:
|
||||
- Line 37: Conditional auth validation (requires specific environment setup)
|
||||
- Line 83: Specific config validation path
|
||||
- Line 132: Static directory not found warning
|
||||
- Line 144: Specific HTTP exception path
|
||||
**Previous Coverage**: 18.45% (225 statements, 173 missing, 84 branches, 3 partial)
|
||||
**New Coverage**: 90.61% (225 statements, 14 missing, 84 branches, 13 partial)
|
||||
|
||||
These remaining lines represent edge cases that would require complex environment manipulation to test and are acceptable to leave uncovered given the 91.75% achievement exceeds the 90% target.
|
||||
#### New Tests Added (27 tests in new file `test_files_view_extended.py`):
|
||||
|
||||
**Test approach**:
|
||||
- Integration testing with TestClient for HTTP handlers
|
||||
- Async context manager testing for lifespan events
|
||||
- Mocking of external dependencies (database, config, notifications)

|
||||
#### Coverage Improvements:
|
||||
- **Main flow**: Files list page with pagination, sorting, filtering
|
||||
- **Detail pages**: File detail with logs, metadata, file existence checks
|
||||
- **File serving**: Preview original/processed files with error handling

|
||||
- Tested actual request/response flows
|
||||
## Test Execution Results
|
||||
|
||||
---
|
||||
All tests passing:
|
||||
- **url_upload tests**: 39 tests passed
|
||||
- **files view tests**: 30 tests passed
|
||||
- **Total**: 69 tests passed, 0 failures
|
||||
|
||||
## Recommendations
|
||||
## Test Quality
|
||||
|
||||
1. **Maintain Coverage**: Add tests for new features to maintain high coverage
|
||||
2. **Edge Cases**: The 4 remaining uncovered lines in main.py are acceptable edge cases
|
||||
3. **CI Integration**: Ensure coverage reports are generated in CI pipeline
|
||||
4. **Documentation**: Keep test docstrings descriptive for future maintainers
|
||||
### Test Structure
|
||||
- Tests organized by feature using pytest classes
|
||||
- Proper use of pytest markers (`@pytest.mark.unit`, `@pytest.mark.integration`, `@pytest.mark.requires_db`)
|
||||
- Clear, descriptive test names following pattern: `test_<what>_<condition>_<expected>`
|
||||
- Comprehensive docstrings for each test
|
||||
|
||||
---
|
||||
### Coverage Focus
|
||||
- **Main usage flows**: File upload, listing, detail viewing, preview, text extraction
|
||||
- **Edge conditions**: Missing files, invalid inputs, network errors, file system errors
|
||||
- **Error handling**: All exception paths covered
|
||||
- **Security**: SSRF protection, filename sanitization, input validation
|
||||
|
||||
## Files Modified
|
||||
### Mocking Strategy
|
||||
- External dependencies properly mocked (requests, Celery tasks)
|
||||
- Database operations use test fixtures with in-memory SQLite
|
||||
- File system operations use pytest's `tmp_path` fixture
|
||||
- No actual HTTP requests or file operations outside test environment
|
||||
|
||||
1. `tests/test_encryption.py` - Added 2 tests
|
||||
2. `tests/test_main.py` - Created new file with 13 tests
|
||||
3. `.gitignore` - Excluded coverage artifacts (if needed)
|
||||
## Files Changed
|
||||
|
||||
---
|
||||
1. **tests/test_url_upload.py** - Added 10 new tests
|
||||
2. **tests/test_files_view_extended.py** - Created new file with 27 tests
|
||||
3. Existing tests in **tests/test_files_view.py** - Maintained (3 tests)
|
||||
|
||||
## Conclusion
|
||||
## Validation
|
||||
|
||||
✅ **All objectives met**:
|
||||
- app/utils/encryption.py: 100% coverage (target: 90%)
|
||||
- app/main.py: 91.75% coverage (target: 90%)
|
||||
- All tests passing
|
||||
- Comprehensive test coverage for logic branches and error/edge cases
|
||||
- Properly documented test cases
|
||||
- No breaking changes to existing functionality
|
||||
Coverage validated with:
|
||||
```bash
|
||||
pytest tests/test_url_upload.py --cov=app/api/url_upload --cov-report=term-missing
|
||||
# Result: 91.21% coverage
|
||||
|
||||
The test suite is now more robust and provides better confidence in code quality and correctness.
|
||||
pytest tests/test_files_view.py tests/test_files_view_extended.py --cov=app/views/files --cov-report=term-missing
|
||||
# Result: 90.61% coverage
|
||||
```
|
||||
|
||||
All tests pass without failures or errors.
