TDD style message expectations; in both RSpec and MiniTest

Your Assignment

In most circumstances like this, there's a sort of MessageBoard. Let's create the idea of a MessageBoard class that both the engineer and the conductor know about.

1. When the conductor sees trouble, the conductor tells the message_board to slow down
2. When the engineer slows down, the engineer tells the message_board confirm_slow_down

Use whichever mocking tool you liked the best or are interested in. If you don't know what to choose, go with RSpec.
