+# Cluster Version Operator Tests
+
+We hold all e2e tests and related common methods in this folder.
+Test script are using client-go, here is the document: https://pkg.go.dev/k8s.io/client-go
+
+## Prerequisites
+- Install golang, the version should match it in go.mod. Here is the how-to doc https://go.dev/doc/install
+- Have the environment variable `KUBECONFIG` set pointing to your cluster.
+
+## Compile the executable binary
+In root folder, run below command to build executable binary:
+```
+$ make update
+```
+The executable binary can be found in ${BIN_PATH} folder, BIN_PATH is set in hack/build-info.sh, in linux it is _output/linux/amd64/ folder.
+
+## Run test case
+
+- Run below command to list all available tests:
+```
+$ _output/linux/amd64/cluster-version-operator-tests list
+```
+Output:
+```
+[jianl@jianl-thinkpadt14gen4 cluster-version-operator]$ _output/linux/amd64/cluster-version-operator-tests list

+- Run below command to execute a test case
+```
+$ _output/linux/amd64/cluster-version-operator-tests run-test <test case name>
+```
+or run test case in one line:
+
+```
+$ _output/linux/amd64/cluster-version-operator-tests list | jq '.[] | select(.name | contains("42543")) | .name' | xargs _output/linux/amd64/cluster-version-operator-tests run-test
