Add test to Set the child prototype... challenge to check for correct output

We could try and add an additional test that would make sure beagle.eat() logs “nom nom nom” to the console

Do you mind if I push this or will you do that?

Not at all, go for it!

@hassaanp that’s almost right and it’s a neat approach. I played with it for a bit and came up with:

  - text: <code>beagle.eat()</code> should log <code>"nom nom nom"</code>
    testString: |
      console.log = function(msg){throw msg;}
      assert.throws(() => beagle.eat(),"nom nom nom");

Since each test is isolated, there’s no need to restore the original console.log.
