Hello!
You’ve not really provided enough code to be able to help entirely, but for
certain I can say you have a problem in your spec.
By calling `after` you are never executing your `current_subject.console`
during your test. So the `expect(current_subject).to receive(:create)` will
always fail your test.
The fact that your test is exiting indicates that the allow is working fine and
its progressing through your console input, as otherwise that loop would never
exit and your test would hang.
Personally this is not how I would test this. Instead I would refactor the code
so that loop causes a step change to occur e.g:
```
def console
loop { process_state(@state) }
end
def process_state(state)
exit unless STATES.include state
public_send(state)
end
```
I would then test process_state in what ever transition you would want, this
avoids the loop. Just make sure you are calling the methods required in your
test and not in `after.
Cheers
Jon Rowe
