CRI Plugin Testing Guide

This document assumes you have already setup the development environment (go, git, containerd/cri repo etc.).

Before sending pull requests you should at least make sure your changes have passed code verification, unit, integration and CRI validation tests.

Code Verification

Code verification includes lint, and code formatting check etc.

  • Install tools used by code verification:
make install.tools

Note: Some make actions (like install.tools) use the user's GOPATH and will otherwise not work when it is not set. Other make actions override it by setting it to a temporary directory for release build and testing purposes.

  • Run code verification:
make verify

Unit Test

Run all unit tests in containerd/cri repo.

make test

Integration Test

Run all integration tests in containerd/cri repo.

make test-integration

CRI Validation Test

CRI validation test is a test framework for validating that a Container Runtime Interface (CRI) implementation such as containerd with the cri plugin meets all the requirements necessary to manage pod sandboxes, containers, images etc.

CRI validation test makes it possible to verify CRI conformance of containerd/cri without setting up Kubernetes components or running Kubernetes end-to-end tests.

make
  • Run CRI validation test:
make test-cri
  • Focus or skip specific CRI validation test:
make test-cri FOCUS=REGEXP_TO_FOCUS SKIP=REGEXP_TO_SKIP

More information about CRI validation test.

Node E2E Test

Node e2e test is a test framework testing Kubernetes node level functionalities such as managing pods, mounting volumes etc. It starts a local cluster with Kubelet and a few other minimum dependencies, and runs node functionality tests against the local cluster.

make test-e2e-node
  • Focus or skip specific node e2e test:
make test-e2e-node FOCUS=REGEXP_TO_FOCUS SKIP=REGEXP_TO_SKIP
