One can use - # an ActionController::Response object to retrieve the current state - # of the response, or customize the response. An Response object can - # either represent a "real" HTTP response (i.e. one that is meant to be sent - # back to the web browser) or a test response (i.e. one that is generated - # from integration tests). See CgiResponse and TestResponse, respectively. - # - # Response is mostly a Ruby on Rails framework implement detail, and - # should never be used directly in controllers. Controllers should use the - # methods defined in ActionController::Base instead. For example, if you want - # to set the HTTP response's content MIME type, then use - # ActionControllerBase#headers instead of Response#headers. - # - # Nevertheless, integration tests may want to inspect controller responses in - # more detail, and that's when Response can be useful for application - # developers.
