How to Run Tests

Quick Start

# Install test dependencies
pip install -r tests/requirements.txt

# Run all unit tests
./tests/run_tests.sh --unit-only

# Run with coverage
./tests/run_tests.sh --unit-only --coverage

# Run using make
make test-unit
make test-coverage

Integration Tests

# Update inventory with device details
cp tests/integration/inventory.ini.example tests/integration/inventory.ini
# Edit inventory.ini

# Run integration tests
./tests/run_tests.sh --integration-only
make test-integration

Next Steps

  1. Install Dependencies: pip install -r tests/requirements.txt
  2. Run Unit Tests: ./tests/run_tests.sh --unit-only
  3. Set Up Integration: Configure tests/integration/inventory.ini
  4. Run Full Test Suite: ./tests/run_tests.sh --all
  5. Generate Coverage: ./tests/run_tests.sh --coverage

Maintenance

The test suite is designed to be:

  • Self-contained: All dependencies clearly defined
  • Maintainable: Well-structured and documented
  • Extensible: Easy to add new tests
  • Reliable: Consistent and reproducible results

For ongoing maintenance, simply:

  1. Add tests for new features
  2. Update existing tests when modifying functionality
  3. Keep mock data current with real API responses
  4. Update documentation as needed

Status: ✅ Complete - Comprehensive testing infrastructure successfully implemented
