**Duration**: 15 minutes

```bash
cd /Users/kooshapari/temp-PRODVERCEL/485/kush/trace

# Install all test dependencies
.venv/bin/python -m pip install \
    pytest \
    pytest-cov \
    pytest-asyncio \
    pytest-mock \
    pytest-xdist \
    pytest-benchmark \
    hypothesis \
    faker \
    factory-boy
```

---

### Step 1.2: Generate Baseline Coverage Report
**Duration**: 30 minutes

```bash
# Run coverage analysis
.venv/bin/python -m pytest \
    --cov=src \
    --cov-report=term-missing \
    --cov-report=html \
    --cov-branch \
    -v

# View HTML report
open htmlcov/index.html
```

**Output**: 
- Terminal coverage summary
- HTML report with detailed coverage by file
- Identified gaps

**Deliverable**: Baseline coverage metrics (likely 50-70%)

---

### Step 1.3: Create Gap Analysis
**Duration**: 30 minutes

   - **CRITICAL**: User, Project, Link, Auth, Error handling
   - **HIGH**: Services, Repositories, CLI, API, Events
   - **MEDIUM**: Utils, Config, Views
   - **LOW**: Logging, Metrics

4. Document in spreadsheet:

| Module | File | Current | Target | Gap % | Critical | Effort |
|--------|------|---------|--------|-------|----------|--------|
| User | src/models/user.py | 60% | 100% | 40% | Yes | 2h |
| UserService | src/services/user_service.py | 65% | 100% | 35% | Yes | 2h |

## Troubleshooting

### Issue: Low Coverage on Module X
**Solution**:
1. Check coverage report: `pytest --cov=src/module --cov-report=term-missing`
2. Identify uncovered lines
3. Create tests for uncovered lines
4. Re-run coverage analysis

### Issue: Flaky Tests
**Solution**:
1. Identify flaky test: `pytest -v --tb=short`
2. Add proper async/await if needed
3. Ensure proper database cleanup
4. Add timeouts if waiting for external services
5. Re-run test 10x to verify stability

### Issue: Slow Tests
**Solution**:
1. Profile test: `pytest --durations=10`
2. Use mocks instead of real database if possible
3. Batch database operations
4. Parallelize execution: `pytest -n auto`
5. Cache expensive test data

### Issue: Coverage Not Enforced in CI/CD
**Solution**:
1. Check GitHub Actions workflow exists
2. Verify pytest.ini has `--cov-fail-under=100`
3. Ensure Codecov action has `fail_ci_if_error: true`
4. Check coverage.xml is generated
5. Review CI/CD logs for errors
