Answer 1

Verify the return value of qDummyServer->listen(). It should return true if the server is indeed listening at port 9000. If it returns false, chances are port 9000 is blocked by another process, and it couldn't listen. In that case, your qTestSocket connected to that other process instead of your own server.
