+# cluster-version-operator-tests
+
+It integrates [openshift-tests-extension](https://github.com/openshift-eng/openshift-tests-extension) to 
+cluster-version-operator which allows openshift components to contribute tests to openshift-tests' suites with
+extension binaries.
+
+
+## Run the tests locally
+
+## Using the framework
+```console
+$ hack/build-go.sh
+$ _output/<OS>/<ARCH>/cluster-version-operator-tests run-suite cluster-version-operator
+```
+
+## Using ginko-cli
+
+After [installing-ginkgo](https://onsi.github.io/ginkgo/#installing-ginkgo):
+
+```console
+$ ginkgo ./test/...
+```
+
+The output looks nicer this way.
