Simulating network outage in tests

[Anand Kumar Sankaran]

Hi

I am implementing a segmentation resolver to handle split brain scenarios.  I 
need to simulate network outages to unit test this behavior.  Any suggestions 
on how to simulate this?  I see that the TcpDiscoverySpi has timeouts, is there 
a way to mock TcpDiscoverySpi to think that there is a network outage to 
simulate such conditions?

Thanks.
