 ## Bootkube E2E Testing
 
 This is the beginnings of E2E testing for the bootkube repo using the standard go testing harness. To run the tests once you have a kubeconfig to a running cluster just execute:
-`go test -v --kubeconfig=<filepath> ./e2e/`
+`go test -v ./e2e/ --kubeconfig=<filepath>`
 
 The number of nodes is required so that the setup can block on all nodes being registered.
