How to test WCF timeout settings?

Question

How can I unit test the effect of each WCF timeout setting? I want to ensure that I select good values and I also want to make sure that my exception handling code is solid.

I created client program and a server WCF service to test the timeout settings. In my service implementation, I added a Thread.Sleep(5000). On the client-side, the only setting that causes a timeout to happen is sendTimeout.

No matter which value I use in all the other settings, the timeout never occurs. How to I test all the other settings?

Here are the settings I would like to test: sendTimeout, receiveTimeout, closeTimeout, openTimeout and inactivityTimeout (in reliableSessions).

Edit 19 feb 2009 : This edit is just to indicate that I still haven't found a way to unit test the WCF timeout settings.

Not a complete answer, but the explanation of the timeout values linked below may be helpful.

If you look in the right place, you can get the channel events and modify your test to be aware of them. Connect is a boolean method on the WCF service. I used svcutil to generate a proxy class using async methods.

private StateManagerClient _stateManagerClient;
private InstanceContext _site;

public New()
{
    _site = new InstanceContext(this);
    _serviceClient = new ServiceClient();
    _serviceClient.ConnectCompleted += ServiceClient_ConnectCompleted;
}

private void ServiceClient_ConnectCompleted(object sender, ConnectCompletedEventArgs e)
{
    //Bind to the channel events
    foreach (IChannel a in _site.OutgoingChannels) {
        a.Opened += Channel_Opened;
        a.Faulted += Channel_Faulted;
        a.Closing += Channel_Closing;
        a.Closed += Channel_Closed;
    }
}

private void Channel_Opened(object sender, EventArgs e)
{
    
}

private void Channel_Faulted(object sender, EventArgs e)
{
    
}

private void Channel_Closing(object sender, EventArgs e)
{
    
}

private void Channel_Closed(object sender, EventArgs e)
{

}

I hope this provides you some value.
