          Problem:
            Can't find original test #{relative_original} for #{relative_original.gsub(/rb$/, Rails::Decorators.extension.to_s)}
          Summary:
            Test decorators need to have the same path as the orignal test.
          Resolution:
            Check that your test decoration has the right path and file name.
