RSpec Tips

Since I’ve been following Jamis Buck’s advice to limit the brittleness of view tests, development has been much more productive. Test the things that matter most else you’ll end up with diminishing returns and the week passed by without any productive work done.

I’m taking one step further and I’ve decided not to write RSpec view specifications.

I will still continue to occasionally test important view elements. It just isn’t worth the extra baggage of writing and maintaining another set of specs for every single view. I’m feeling the pain there and I’m taking steps to eliminating it.

But it is also painful to sprinkle “integrate_views” syntactic vinegar throughout controller specifications. I don’t want to do without that since I would still get notified of template errors. Unfortunately, this is not the recommended behavior and not much was written on the subject.

Peter Marklund has a solution but it didn’t work for me. Maybe because RSpec was updated since his blog post was written but it is more likely that I’m missing something obvious. However, I dug around the plugin and was happy to discover a simple method override that worked. Add to spec_helper.rb:

module Spec
  module Rails
    module Example
      class ControllerExampleGroup
        module ControllerInstanceMethods
          def integrate_views?
            true
          end
        end
      end
    end
  end
end

btw, while browsing the RSpec mailing list, I came across a post that explains a way to slightly speed up test runs.
