#CODE

    class Light

     def on?
      false
     end

     def turn_on
      true
     end
    end

I know this is very basic as far as trying to get the test to pass but what am I missing?

So basically it's saying, the light is initially off, then after you define and call on the turn_on method, the light should be on. So, the first test should be false, and the 2nd test should be true after the method is run.

For some reason, I don't know how to go about putting that into code.
