These tests should make sure the socket was created in the right socket pool.

Should probably also have proxy tests, to make sure the right socket pools are
used.

[yhirano, 2013/05/27 09:21:32]

Done.
Since net::InitSocketHandleForHttp is responsible for the pool selection, we
only check parameters for the function.
I may modify InitSocketHandleForHttp parameters in a future CL.
