Can you list the main types of tests and checks used in Kubernetes?

Various types of tests and checks are used in Kubernetes to ensure cluster stability and reliability:

• Unit tests: test individual components and functions of Kubernetes code.
• Integration tests: verify interactions between components.
• End-to-End (E2E) tests: simulate real cluster usage scenarios, testing the operation of all components together.
• Conformance tests: check the cluster's compliance with Kubernetes standards to guarantee compatibility.
• Static analysis and linting: check configurations and manifests for errors and inconsistencies.
• Health checks and readiness/liveness probes: built-in mechanisms to verify the state of pods and services within the cluster.

These tests help identify errors at various levels and ensure the stable operation of applications in Kubernetes.
