rspec users - May 2011 - api (class/method) renaming, will a simple controller test verify this?

I want my tests to fail if I rename a method in my /lib folder in a rails
app.

Say I have a class like:

/lib
/lib/formatter.rb

class Formatter
   def self.do_transforms(text)
      text
   end
end


And say I reference this in my HomeController''s index action:


def index

    text = params[:text]

    text = Formatter.do_transforms(text)


end


Now if I was to rename the method from do_transforms to perform_transforms,
what is the minimum test I would neeed to do on my HomeController to get it
to fail b/c of the rename?

The simplest test that would cover your specific case would probably be:

  describe HomeController do
    describe "GET ''index''" do
      it "succeeds" do
        get :index
        response.should be_success
      end
    end
   end

If the method has been renamed, the index action will throw a
NoMethodError and that spec will fail.
