About:
KUTTL is a declarative testing framework specifically designed for Kubernetes Operators and Controllers. It allows developers to define test scenarios using Kubernetes manifests, enabling automated validation of operator behavior without writing complex code. The tool simplifies the process of testing complex stateful applications and custom resources in Kubernetes environments.
Key Features:
  • Declarative test syntax using YAML
  • Built-in assertions for Kubernetes resources
  • Support for test hooks and parallel execution
  • Integration with kubectl and kustomize
  • Test report generation
Use Cases:
  • End-to-end testing of Kubernetes Operators
  • Validating Custom Resource Definitions (CRDs)
  • Testing Helm chart deployments
  • Continuous integration pipelines for Kubernetes applications
Alternatives:
  • kind – kind creates local clusters but doesn't provide testing framework
  • testkube – Testkube is a Kubernetes-native testing framework but focuses on general test execution
  • sonobuoy – Sonobuoy runs Kubernetes conformance tests but isn't designed for custom operator testing
