In two steps:
1. Setup all necessary attributes of a server in setUp(), including
the ones that are not faked in FaseServer by default.
2. Run a similar process with no option test case.
The future plan is to move all these attributes to FakeServer.
But it will cause some other changes which has nothing to do with
this patch. So leave this job to do later.
