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
