bypass_rescue.feature

Feature: bypass rescue

  Use `bypass_rescue` to bypass both Rails' default handling of errors in
  controller actions, and any custom handling declared with a `rescue_from`
  statement.

  This lets you specify details of the exception being raised, regardless of
  how it might be handled upstream.
