Asserts that the response is one of the following types:

• :success - Status code was 200
• :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 ActionController::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
