Unit test your Kubernetes Custom Resource Definitions (CRDs) 🛠️

testcrd

Unit test your Kubernetes Custom Resource Definitions (CRDs) against concreate resource samples without a need for a running Kubernetes cluster.

The primary use case would be to ensure backward-compatibility of CRD changes.

Installation

go get github.com/roma-glushko/testcrd

import (
	"github.com/roma-glushko/testcrd"

	_ = asserter.LoadFromFiles([]string{

	})

	_ = asserter.AssertFiles(t, []string{
		"fixtures/my_crd/resource.sample.yaml",
	})
