## 📊 Test Execution

### Quick Test

```bash
# Run all tests
python -m pytest tests/ -q

# Expected: 932 passed in ~15s (or 783 base tests)
```

### With Coverage

```bash
python -m pytest tests/ --cov=hearthnet --cov-report=html --cov-report=term
open htmlcov/index.html
```

### Specific Module

```bash
# Enhanced LLM tests
python -m pytest tests/test_m04_enhanced.py -v

# All Phase 1
python -m pytest tests/test_m0*.py tests/test_x0*.py -v
```

### Before Commit

```bash
bash pre-commit-hook.sh
# Tests run automatically
git commit -m "..."  # ← fails if tests fail
```

---

## 🔧 CI/CD Configuration

### GitHub Actions (.github/workflows/test.yml)

**Triggers:**
- Push to `main` / `dev` branches
- All pull requests
- Manual trigger (workflow_dispatch)

**Actions:**
1. Checkout code
2. Set up Python (3.10, 3.11, 3.12)
3. Install dependencies
4. Run tests with coverage
5. Upload coverage to Codecov
6. Comment on PR with results

**Status badge in README:**
```markdown
[![Tests](https://github.com/ckal/HearthNet/workflows/Test%20Suite%20%26%20Coverage/badge.svg)](https://github.com/ckal/HearthNet/actions)
```

### Local Pre-Commit Hook

**Setup:**
```bash
cp pre-commit-hook.sh .git/hooks/pre-commit
chmod +x .git/hooks/pre-commit
```

**Behavior:**
- Runs before every `git commit`
- Executes: `python -m pytest tests/ -q --tb=short`
- Aborts commit if tests fail
- User must fix and retry

## 🎯 Next Steps (Future Phases)

To further improve test coverage and real implementations:

### Phase 4: Real Implementation of Scaffolds
1. Replace pass statements in M14-M32 tests with real code
2. Implement X05-X09 cross-cutting tests
3. Add reference documentation tests (contract, glossary, etc.)
4. Target: 50-60% coverage

### Phase 5: Advanced Testing
1. Integration tests between modules
2. Load/stress testing (1000+ messages)
3. Network failure simulations
4. Performance benchmarking
5. End-to-end scenarios

### Phase 6: Monitoring
1. Continuous coverage tracking
2. Performance regression detection
3. Automated test report generation
4. Coverage trend analysis
