Unknown Webrat application_framework: #{Webrat.configuration.application_framework.inspect}

Please ensure you have a Webrat configuration block that specifies an application_framework
in your test_helper.rb, spec_helper.rb, or env.rb (for Cucumber).

For example:

  Webrat.configure do |config|
    # ...
    config.application_framework = :rails
  end
      STR
        end
      end

    end

  end
