def assert_redirected_to(options = {}, message = nil)
  assert_response(:redirect, message)
  return true if options === @response.location

  redirect_is       = normalize_argument_to_redirection(@response.location)
  redirect_expected = normalize_argument_to_redirection(options)

  message ||= "Expected response to be a redirect to <#{redirect_expected}> but was a redirect to <#{redirect_is}>"
  assert_operator redirect_expected, :===, redirect_is, message
end

#assert_response(type, message = nil) ⇒ Object

Asserts that the response is one of the following types:

  • :success - Status code was in the 200-299 range

  • :redirect - Status code was in the 300-399 range

  • :missing - Status code was 404

  • :error - 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 Rack::Utils::SYMBOL_TO_STATUS_CODE for a full list.

# Asserts that the response was a redirection
assert_response :redirect

# Asserts that the response code was status code 401 (unauthorized)
assert_response 401
