Maybe you don't need to use the same *value* in both places Step 5: when you're sure that you want to use the same value in multiple unrelated specs, move it into a class defined in a spec_helper-ish thing Underlying principles: * Don't duplicate the hardcoded path, but * Keep the scope of the path as narrow as possible at all times -- J.
