[mocha-developer] Mocking to spec a sort_by method

[Zach Moazeni]

I think you're meaning to do

vehical1.stubs(:[]).with(;mph).returns(150)
vehical2.stubs(:[]).with(;mph).returns(250)

Or in your prod code write vehicle.send(:mph) instead of vehical[symb]

Also in your test you should probably be doing comparer.add_vehical 
([vehical1, vehical2]) instead of @vehical1, @vehical2

Hope that helps.
