    WARNING_MESSAGE = <<-EOS.freeze
      This usage of the Code Climate Test Reporter is now deprecated. Since version
      1.0, we now require you to run `SimpleCov` in your test/spec helper, and then
      run the provided `codeclimate-test-reporter` binary separately to report your
      results to Code Climate.

      More information here: https://github.com/codeclimate/ruby-test-reporter/blob/master/README.md
