How to validate a REST request, ideally which should not return anything?

Hi,

I am validating a REST request. For my scenario, ideally, the REST request should not return anything. Any how i am not getting any response.

But after 2 mins of "Socket timeout" test case is getting failed. How can i validate this negative scenario?

I would like to use an assertion to validate the request, which should not return anything.

Thank you in advance
