Testing

In order to run all tests in this package you must set the REMOTE_CLUSTER_CONTEXT env var to the name of a context in your kubeconfig. To quickly provision two kind clusters for testing, run ./ci/setup-kind.sh <remote-context-name>. This will create two kind clusters, skv2-test-master and <remote-context-name>, and set your current context to kind-skv2-test-master. To run the multicluster tests in this package, you can then use REMOTE_CLUSTER_CONTEXT=kind-<remote-context-name> TEST_PKG=codegen/render make run-tests. To cleanup the kind clusters, run ./ci/teardown-kind.sh.
