Subject re: A question about Unit Test
Date Tue, 10 May 2011 07:58:41 GMT
Thanks for your reply.

1/  I have other question: It needs clear something when one test case had failed ?
    In my case. The test cases auto run at night.
    I find some test case failed randomly and try to dig it.

Did you try it Gao?  The below looks like it might be a little
'dangerous' in that an empty address happens when the hosted
InetSocketAddress fails to resolve.  Which test is failing?  We should
for sure make it so tests pass if you are not connected to the net.

Thanks Gao,
