Here you are not performing any actions or calling any methods.
All you are doing with this message expectation is saying that for this test to pass, the message_board should receive a call of slow_down!
The normal flow here would be to then execute some code to see if it happened.
it "should receive slow down from conductor" do
message_board.should_receive(:slow_down!)
conductor.see_danger_coming!
end

Okay so I fixed that but what really gets me is that I am not really understanding the arguments error. Is there somewhere I can read up on that? I have found little by searching my error message. Same for "matches?" too. |

You could specify the exact argument you want. For example, if you wanted to make sure the AnswerBank received the answer 42, you could: answer_bank.should_receive(:record_answer).with(42)By default, it will accept "any_arguments" if you do not specifiy. |

Is this a valid specification?
It COULD be, if you write it. That is, if you created a customer matcher... But you didn't, so you got an error about a "matcher"

Hmmm. Okay, how do my tests look? Am I on the right track? |
|
Yep, you're on the right track! |

Sorry I am dong so many at one time but wanted to go over some core concepts before I got started with my MVP. I'm looking into "any args" and am only getting more confused. Do you suggest any resources or am I over-thinking this? |

IMHO you are way over-thinking this. But, if you want to see the documentation: https://www.relishapp.com/rspec/rspec-mocks/docs/message-expectations/expect-message-using-should-receive#expect-a-message-with-an-argument |

I'm wondering in RSpec if the previous tests pass before you move on to next test. That way, I can see that since Engineer and Conductor have already had their actions I do not need them again in MessageBoard. But then, I seem to get the wrong number of arguementts and don't exactly know what I should be passing in.
