A small suite of assertions that test responses from Rails applications.
Assert that the redirection options passed in match those of the redirect called in the latest action. This match can be partial, such that assert_redirected_to(:controller => "weblog") will also match the redirection of redirect_to(:controller => "weblog", :action => "show") and so on.
# assert that the redirection was to the "index" action on the WeblogController assert_redirected_to :controller => "weblog", :action => "index" # assert that the redirection was to the named route login_url assert_redirected_to login_url # assert that the redirection was to the url for @customer assert_redirected_to @customer

Asserts that the response is one of the following types:
You can also pass an explicit status number like assert_response(501) or its symbolic equivalent assert_response(:not_implemented). See ActionController::StatusCodes for a full list.
# assert that the response was a redirection assert_response :redirect # assert that the response code was status code 401 (unauthorized) assert_response 401

Asserts that the request was rendered with the appropriate template file.
