I was thinking about "A factory to create a MockQuicStreamRequest." or something
similar.  (Because this class is not a mock QuicStreamRequest.)

[xunjieli, 2017/05/03 22:18:29]

Acknowledged. With Ryan's help, I am able to use MockQuicData which is more
consistent with other quic tests (e.g. QuicNetworkTransactionTest).
