Codebase Review for Test Coverage

Current Status: 42/44 tests passing (95.5% success rate)

Areas to Review:

1. Untested Functionality: Identify any features without E2E tests
2. Edge Cases: Look for error scenarios not covered
3. Integration Points: Check component interaction testing
4. Performance Testing: Consider load time and bundle size tests
5. Accessibility Testing: Check for a11y compliance

Files to Review:

• src/js/ - All JavaScript modules
• src/html/ - HTML templates and workbench
• cypress/e2e/ - Existing test coverage
• cypress/fixtures/ - Test data completeness

Acceptance Criteria:

• All major functionality has E2E test coverage
• Error scenarios are properly tested
• Integration points are validated
• Performance metrics are tracked
• Accessibility requirements are met

Implementation Plan:

1. Review all source files for untested features
2. Create tests for identified gaps
3. Add performance and accessibility tests
4. Update documentation with coverage report
