The test expects a `page_title` method to be called in every template. It doesn't actually check the title is set, just that the call is present in the Erb file. I implemented `new` and `edit` and then refactored them both to use the same `_form` partial. Due to duplication of the heading text (e.g. "Create a new firble") inside the `_form` partial I wanted to move both places that it was used inside `_form.html.erb`; the `page_title` call is no longer in the action's Erb file, and the test failed.

I didn't think WET-ing up the code was the best solution (though I did try it).
