Test Case: Session Client General Service Behaviour: 007

Test case Description: Ensure that the client is setting the timeoutHint to a useful value.

Expected Result: TimeoutHint shall be set high enough to allow the server the processing of the request and providing a response. E.g. setting the timeoutHint to a few ms would timeout the request before the being received by the server in many cases.

The current test case suggests keeping the timeoutHint to a useful value. I want to know whether is it really necessary to set it to any value or will it be fine, if it is to 0.

As it says – it needs to be useful. 0 is not useful.

Anyone designing a client will have a timeout set on all network calls. It would be poor programming practice if you did not. This timeout is often the most appropriate value for the timeoutHint.
