+## Testing
+
+### CI/CD Testing
+
+Sentrius includes comprehensive CI/CD testing for Helm charts and Java builds:
+
+- **Automated testing** runs on every push and pull request via GitHub Actions
+- **Helm chart validation** including linting, template rendering, and schema validation
+- **Integration testing** with Kubernetes clusters for deployment validation
+
+### Local Testing
+
+Test Helm charts locally before deployment:
+
+    # Test all charts
+    ./ops-scripts/test-helm-charts.sh
+
+    # Test specific aspects
+    ./ops-scripts/test-helm-charts.sh lint      # Lint charts
+    ./ops-scripts/test-helm-charts.sh template  # Test rendering
+    ./ops-scripts/test-helm-charts.sh config    # Test configurations
+
+For detailed testing documentation, see [docs/helm-testing.md](docs/helm-testing.md).
