Run Test Suite

You are responsible for running the test suite to verify code quality and correctness.

Your Task

1. Identify the project - Determine if changes are in hotel-de-ville, shadow-api, or stellaris
2. Identify component - Backend (pytest) or frontend (Playwright/vitest)
3. Navigate to project directory
4. Activate virtual environment if backend, or install deps if frontend
5. Run appropriate tests
6. Report results clearly

Docker Isolation (Preferred)

When Docker is available, prefer running tests in containers for isolation.

Docker Test Protocol

1. Check for Docker availability:
   if command -v docker &> /dev/null && docker info &> /dev/null; then
       USE_DOCKER=true
   fi

2. Check for Dockerfile:
   if [ -f "Dockerfile" ] || [ -f "Dockerfile.test" ]; then
       DOCKER_AVAILABLE=true
   fi

3. If Docker available:
   # Build test image
   docker build -t test-runner:latest -f Dockerfile.test .

   # Run tests in container
   docker run --rm -v $(pwd):/app test-runner:latest pytest -v

   # Compare deps in container vs requirements.txt
   docker run --rm test-runner:latest pip freeze > /tmp/container_deps.txt
   diff requirements.txt /tmp/container_deps.txt

4. If Docker NOT available:
   # Warn prominently
   echo "⚠️ WARNING: Running tests on host, not in Docker container"
   echo "Dependencies may differ from production environment"
   # Fall back to host execution

Dependency Verification

When using Docker, verify dependencies match:

# Get installed packages in container
docker run --rm test-runner pip freeze | sort > /tmp/container.txt

# Get requirements
sort requirements.txt > /tmp/required.txt

# Check for undeclared dependencies (in container but not in requirements)
comm -23 /tmp/container.txt /tmp/required.txt > /tmp/undeclared.txt

if [ -s /tmp/undeclared.txt ]; then
    echo "⚠️ UNDECLARED DEPENDENCIES FOUND:"
    cat /tmp/undeclared.txt
    echo ""
    echo "These packages are installed but not in requirements.txt"
    echo "Tests may pass locally but fail in production"
fi

Docker vs Host Decision Matrix

Execution Steps (Host Fallback)

For hotel-de-ville/backend

cd /home/user/jf-private/hotel-de-ville/backend

# Warn if not using Docker
echo "⚠️ Running tests on host (Docker not available)"

# Activate venv if exists
if [ -d "venv" ]; then
    source venv/bin/activate
fi

# Run tests with coverage
pytest -v --tb=short

For shadow-api

cd /home/user/jf-private/shadow-api

# Warn if not using Docker
echo "⚠️ Running tests on host (Docker not available)"

# Activate venv if exists
if [ -d "venv" ]; then
    source venv/bin/activate
fi

# Run tests with coverage
pytest -v --tb=short

For stellaris/backend

cd /home/user/jf-private/stellaris/backend

# Warn if not using Docker
echo "⚠️ Running tests on host (Docker not available)"

# Activate venv if exists
if [ -d "venv" ]; then
    source venv/bin/activate
fi

# Run tests with coverage
pytest -v --tb=short

For stellaris/frontend (Playwright E2E tests)

cd /home/user/jf-private/stellaris/frontend

# Install dependencies if needed
npm install

# Run Playwright tests
npx playwright test --reporter=list

IMPORTANT for Stellaris Frontend: Playwright tests exist in stellaris/frontend/tests/ and test:

• Chapter selection behavior
• Training mode navigation
• Session completion
• Stats persistence
• Vocabulary browser

Reporting Results

After running tests, provide a clear summary:

If all tests pass:

✅ Test Suite Passed

Project: hotel-de-ville/backend
Tests run: 23
Passed: 23
Failed: 0
Duration: 2.3s

All tests passed successfully. Code is ready for commit.

If tests fail:

❌ Test Suite Failed

Project: shadow-api
Tests run: 15
Passed: 12
Failed: 3

Failed tests:
1. test_pipeline.py::test_atomize_stage - AssertionError: BLUF missing
2. test_retrieval.py::test_dual_embedding - IndexError: list index out of range
3. test_integration.py::test_full_pipeline - ValueError: Invalid source_type

⚠️ Fix these failures before committing.

Additional Checks

If tests pass, you may also:

• Check for warnings in test output
• Note if coverage has decreased (if pytest-cov is available)
• Suggest running specific test files if only partial changes were made

When NOT to Invoke

• For non-code changes (markdown files, documentation only)
• When user explicitly says "skip tests" or "don't run tests"
• For trivial changes like comment updates or formatting

Priority

This is a HIGH PRIORITY skill. Code quality depends on passing tests. Always run tests before suggesting commits or marking features as complete.
