In Locust I need to get original timeout or connection error when using catch_response=True to validate response

Question

There is a good explanation how to validate response of the request https://docs.locust.io/en/stable/writing-a-locustfile.html#validating-responses

However there are cases when status_code=0 (case of connection error or timeout). I would like to be able to pass original error when it happens in response.failure(). For example:

with self.client.get("/some_test_url/", catch_response=True) as response:
    if response.status_code == 200 and _some_other_errors_checks_:
        response.failure("Response is 200 but contain _some_error_")
    if response.status_code == 0: # This is case of timeout or connection error
        response.failure(????????)

Answer 1

You could see the original error using response.error property.

If something happened and the response is an error response or contains an error you could raise the original error using response.raise_for_status() that will throw the original error of the response if exists
