+
+## Test Commands
+
+### Basic Test Execution
+
+```bash
+# All tests (recommended for CI)
+pytest
+
+# Only integration tests (system-level)
+pytest tests/integration/
+
+# Only unit tests (fast)
+pytest tests/unit/
+
+# Verbose output
+pytest -v
+
+# Show test coverage
+pytest --cov=mlx_knife --cov-report=html
+```
+
+### Specific Test Categories
+
+```bash
+# Process lifecycle tests (critical for production)
+pytest tests/integration/test_process_lifecycle.py -v
+
+# Health check robustness (model corruption detection)
+pytest tests/integration/test_health_checks.py -v
+
+# Core functionality (basic CLI commands)
+pytest tests/integration/test_core_functionality.py -v
+
+# Advanced run command tests
+pytest tests/integration/test_run_command_advanced.py -v
+
+# Server functionality tests
+pytest tests/integration/test_server_functionality.py -v
+```
+
+### Test Filtering
+
+```bash
+# Run only basic operations tests
+pytest -k "TestBasicOperations" -v
+
+# Skip server tests (faster)
+pytest -k "not server" -v
+
+# Skip tests requiring actual models
+pytest -k "not requires_model" -v
+
+# Run only process lifecycle tests
+pytest -k "process_lifecycle or zombie" -v
+
+# Run health check tests only
+pytest -k "health" -v
+```
+
+### Timeout and Performance
+
+```bash
+# Set custom timeout (default: 300s)
+pytest --timeout=60
+
+# Show slowest tests
+pytest --durations=10
+
+# Parallel execution (if pytest-xdist installed)
+pytest -n auto
+```

+5. **CI/CD Integration**: Automated testing pipeline
+
+## CI/CD Integration
+
+### GitHub Actions Example
+```yaml
+name: Tests
+on: [push, pull_request]
+jobs:
+  test:
+    runs-on: macos-latest
+    strategy:
+      matrix:
+        python-version: ["3.10", "3.11", "3.12", "3.13"]
+    steps:
+      - uses: actions/checkout@v4
+      - name: Set up Python
+        uses: actions/setup-python@v4
+        with:
+          python-version: ${{ matrix.python-version }}
+      - name: Install dependencies
+        run: pip install -e ".[test]"
+      - name: Run tests
+        run: pytest tests/integration/ -v --timeout=120
+```
+
+### Local Pre-commit Testing
+```bash
+#!/bin/bash
+# test-local.sh - Run before committing
+set -e
+
+echo "Running MLX Knife test suite..."
+
+# Quick smoke test
+pytest tests/integration/test_core_functionality.py::TestBasicOperations -v
+
+# Process hygiene (critical)
+pytest tests/integration/test_process_lifecycle.py -v
+
+# Health checks (critical) 
+pytest tests/integration/test_health_checks.py -v
+
+echo "✅ Core tests passed. Safe to commit."
+```
+
+## Development Testing
+
+### Adding New Tests
+1. **Integration tests** go in `tests/integration/`
+2. **Unit tests** go in `tests/unit/`
+3. Use existing fixtures from `conftest.py`
+4. Follow naming: `test_*.py`, `Test*` classes, `test_*` methods
+
+### Test Categories (Markers)
+```python
+@pytest.mark.integration  # Slower system tests
+@pytest.mark.unit         # Fast isolated tests  
+@pytest.mark.slow         # Tests >30 seconds
+@pytest.mark.requires_model  # Needs actual MLX model
+@pytest.mark.network      # Requires internet
+```
+
+### Mock Utilities
+- `mock_model_cache()`: Creates fake model directories
+- `mlx_knife_process()`: Manages subprocess lifecycle
+- `process_monitor()`: Tracks zombie processes
+- `temp_cache_dir()`: Isolated test environment
+
+## Test Philosophy
+
+Following the **"Process Hygiene over Edge-Case Perfection"** principle:
+
+1. **Process Cleanliness**: No zombies, no leaks ✅
+2. **Health Checks**: Reliable corruption detection ✅  
+3. **Core Operations**: Basic functionality works ✅
+4. **Error Handling**: Graceful failures (improving)
+
+The current test suite successfully validates production readiness while identifying specific areas for enhancement.
+
+## Troubleshooting
+
+### Common Issues
+```bash
+# Tests hang forever
+pytest --timeout=60
+
+# Import errors
+pip install -e ".[test]"
+
+# Process cleanup issues  
+ps aux | grep mlx_knife  # Check for zombies
+
+# Cache conflicts
+export HF_HOME="/tmp/test_cache"
+```
+
+### Test Environment
+```bash
+# Clean test run
+rm -rf .pytest_cache __pycache__
+pytest tests/ -v --cache-clear
+
+# Debug specific test
+pytest tests/integration/test_health_checks.py::TestHealthCheckRobustness::test_healthy_model_detection -v -s
+```
