Checking method presence/arity?

[Jeff Winkler]

Hi-

 Recently watched Sandy Metz's video about testing magic tricks - http://www.youtube.com/watch?feature=player_detailpage&v=URSWYvyc42M#t=1670

 She talks about using a mocking library that protects against API drift by checking that the mock has the same contract. Is there any way to do this in Mocha? 

This test passes, but I'd like it to blow up saying you can't mock a method that's not on the underlying object. --

class Foo

end

describe Foo do

  it 'should mock' do

    f=Foo.new

    # mock a non-existent method.

    f.expects(:missing_method).with(1).returns(1)

    f.missing_method(1).must_equal 1

  end

end

Thanks

Hi Jeff,

I've certainly have it in mind for a while - https://github.com/freerange/mocha/issues/149. If only I had the time to implement it!

If you're interested, perhaps you could submit a pull request with some suggested changes...? Or perhaps add some comments to that issue...?

Cheers, James.
