+## 🧪 Testing
+
+BabelBridge has a comprehensive test suite covering both backend and frontend components.
+
+### Test Coverage
+
+- **Go Backend**: Unit tests, integration tests, and mock testing
+- **Frontend**: Component tests, context tests, utility tests, and E2E tests
+- **Coverage Target**: 70%+ for both backend and frontend
+- **Status**: 100% passing tests ✅
+
+### Running Tests
+
+#### All Tests
+```sh
+make test-all          # Run all tests with coverage
+npm run test:all       # Alternative using npm (frontend only)
+```
+
+#### Go Backend Tests
+```sh
+make test-go           # Run Go tests with coverage
+go test -v ./...       # Basic test run
+go test -cover ./...   # With coverage
+```
+
+#### Frontend Tests  
+```sh
+make test-frontend     # Run frontend tests with coverage
+cd frontend && npm test               # Unit tests (watch mode)
+cd frontend && npm run test:unit      # Unit tests (single run)
+cd frontend && npm run test:coverage  # With coverage report
+```
+
+#### E2E Tests
+```sh
+make test-e2e          # Run end-to-end tests
+cd frontend && npm run test:e2e       # Direct E2E run
+cd frontend && npm run test:e2e:ui    # E2E with UI
+```
+
+### Coverage Reports
+
+After running tests with coverage, reports are available at:
+- **Go**: `coverage.html` (root directory)
+- **Frontend**: `frontend/coverage/index.html`
+
+### Continuous Integration
+
+All tests run automatically on:
+- ✅ Every push to main/develop branches
+- ✅ Every pull request
+- ✅ Coverage reports posted as PR comments
+- ✅ Tests must pass before merging
