module Assertions
# A small suite of assertions that test responses from Rails applications.
module ResponseAssertions
# Asserts that the response is one of the following types:
#
# * <tt>:success</tt> - Status code was 200
# * <tt>:redirect</tt> - Status code was in the 300-399 range
# * <tt>:missing</tt> - Status code was 404
# * <tt>:error</tt> - Status code was in the 500-599 range
#
# You can also pass an explicit status number like assert_response(501)
# or its symbolic equivalent assert_response(:not_implemented).
# See ActionDispatch::StatusCodes for a full list.
#
# ==== Examples
#
# # assert that the response was a redirection
# assert_response :redirect
#
# # assert that the response code was status code 401 (unauthorized)
# assert_response 401

# ==== Examples
