Here ^^ random_string is being called in the context of the example,
not the Sinatra::Application class or any of its instances. I don't
know how Sinatra includes helper modules, but assuming that includes
them in the Sinatra::Application object, then this should work:
Sinatra::Application.should_receive(:random_string).with(6).and_return('abcdef')
Sinatra::Application.random_string(6).should eq 'abcdef'
