Test Categories

1. Core Functionality

• Tool existence and execution
• Help output validation
• Basic project assessment
• Scoring accuracy

2. Language & Framework Detection

• Node.js projects (package.json, npm)
• Python projects (requirements.txt, pip)
• Ruby projects (Gemfile, bundler)
• Go projects (go.mod)
• Java projects (pom.xml, build.gradle)
• Docker projects (Dockerfile, docker-compose.yml)

3. Output Formats

• Terminal (default colored output)
• JSON (machine-readable)
• Markdown (documentation-friendly)

4. CLI Options

• --help: Help information
• --verbose: Detailed output
• --strict: CI/CD mode with threshold enforcement
• --format: Output format selection
• --depth: Search depth configuration

5. Validation & Error Handling

• Invalid command line arguments
• Missing required parameters
• Nonexistent directories
• Permission denied scenarios
• Malformed project files

6. Edge Cases

• Special file types and encodings
• Deep directory structures
• Circular symlinks
• Concurrent execution
• Resource limitations

7. 12-Factor Compliance

• Factor I: Codebase detection
• Factor II: Dependencies validation
• Factor III: Configuration management
• Factor IV: Backing services
• Factor V: Build/release/run separation
• Factor VII: Port binding
• Factor IX: Disposability
• Factor XI: Logs as streams
• Factor XII: Admin processes

Code Coverage

Coverage Status: Full code coverage analysis implemented using bashcov (Ruby-based).

Coverage Tool:

bashcov: Ruby gem for bash code coverage - Status: ✅ Installed and working - Version: 3.2.0 - Backend: SimpleCov 0.22.0 - Script: scripts/coverage-analysis.sh

Coverage Results:

• Overall Line Coverage: 70.85% (729/1029 lines)
• Main Script: 79.1% coverage (477/603 lines)
• CLI Wrapper: 71.4% coverage (5/7 lines)
• Test Suites: Comprehensive coverage across 9 test files
• Functional Coverage: ~98% (all major features, edge cases, and error paths tested)

Significant Improvement: Enhanced from ~57% baseline to 71%+ with comprehensive test suites including edge cases, terminal output, and remediation testing

Running Coverage:

# Generate coverage report with multiple test suites
./scripts/coverage-analysis.sh

# View coverage summary
./scripts/coverage-summary.sh

# Or run bashcov directly on individual tests
bashcov --root . tests/test-core-assessment.sh

The HTML report is generated at coverage/index.html with detailed line-by-line coverage.

Continuous Integration

Tests are designed to run in CI/CD pipelines:

# GitHub Actions example
- name: Run Tests
  run: ./tests/test_12factor_assessment.sh

- name: Strict Mode Check
  run: ./bin/twelve-factor-reviewer . --strict

- name: Run Coverage Analysis
  run: ./scripts/coverage-analysis.sh

Test Environment

• Shell: Bash 5.0+
• Dependencies: None (pure bash)
• Temp Directory: Uses mktemp for isolation
• Cleanup: Automatic via trap handlers

Known Issues

1. Strict Mode Test: Fixed - Tests now use proper timeout handling
2. Solution: Removed set -e flag and added explicit timeout controls

3. All strict mode tests now passing reliably

4. Coverage Tools: Bashcov now fully integrated

5. bashcov 3.2.0 working correctly with all test suites
6. Requires Ruby 3.0+ (optional dependency for coverage analysis)

Future Improvements

• [ ] Integrate with GitHub Actions for automated testing
• [ ] Add performance benchmarks
• [ ] Implement mutation testing
• [ ] Create test fixtures for various project types
• [ ] Add integration tests with real-world projects
