+## Testing & CI/CD
+
+MineSeeker has a comprehensive test suite with **71 automated tests** and continuous integration/deployment pipelines.
+
+### Quick Start
+
+```bash
+# Setup test database (first time only)
+make test-db-setup
+
+# Run all tests
+make test
+
+# Run with documentation output
+vendor/bin/phpunit --testdox
+```
+
+### Test Suite
+
+- **71 tests** with **227 assertions**
+- **Controller tests** - HTTP endpoints, authentication, routing
+- **DTO tests** - Data serialization and calculations
+- **Entity tests** - Domain logic and defaults
+- **Service tests** - Business logic and external APIs
+- **Integration tests** - Foundry factories and database isolation
+
+**Test execution time:** ~6-8 seconds
+
+### Continuous Integration
+
+**Automated testing** runs on every push/pull request:
+
+```yaml
+# .gitea/workflows/ci.yml
+✓ PHP 8.3 setup with all extensions
+✓ PostgreSQL 18 service container
+✓ Composer and npm dependency installation
+✓ Asset building with Vite
+✓ Database migrations
+✓ Full test suite execution
+✓ Code linting (ESLint, PHP-CS-Fixer)
+```
+
+### Continuous Deployment
+
+**Automated deployment** on version tags (e.g., `v1.2.3`):
+
+```yaml
+# .gitea/workflows/deploy.yml
+1. Run full test suite (blocks deployment if fails)
+2. Checkout tagged version
+3. Build Docker image
+4. Run database migrations
+5. Restart services
+6. Health check verification
+```
+
+**Deploy to production:**
+```bash
+git tag -a v1.2.3 -m "Release version 1.2.3"
+git push origin v1.2.3
+```
+
