assert_response

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.

# assert that the response was a redirection
assert_response :redirect
