Can you provide some additional context regarding where you are seeing this message? Is it related to a call to create() or run_test()?
Since you indicated you are trying to create a component named ‘test’, I’m going to guess it is related to the run_test() call. If this is the case, did you make sure that you imported your package containing your test? If the package isn’t imported, it won’t be able to create a component of that type.
