Testing rescue_action_in_public tip

Hi All,

Here's a trick to functional test rescue_action_in_public, I've been searching in the Rails source for an hour to find it:

get(:index) @controller.send(:erase_render_results) @controller.send(:rescue_action_in_public, ActionController::RoutingError.new(nil))

Calling erase_render_results after the get lets you call rescue_action_in_public without getting DoubleRender errors. This for example allows you to test if exception notification emails are sent properly or if the right 404 page is rendered.

grtz

Thijs
