Induce WCF openTimeout closeTimeout

Question

I wish to test and observe timeout behaviours between a WCF client and service host. For receiveTimeout and sendTimeout, it is probably easy to transmit a large byte stream that takes more than a few seconds and set those timeout attributes to ridiculously low values.

However, since there is nothing that can be done beyond the calling of a serviceProxy.Open() or .Close() methods, I am thinking what is a good way to delay the opening and closing of WCF connections, to cross the thresholds of openTimeout and closeTimeout?

Well, if you have exposed your contracts correctly (as interfaces), you can mock an instance of the proxy which throws TimeoutException and pass it to your code for use.
