Why do you pass TWO_CLIENT_LEGACY? Could you try running with TWO_CLIENT?

[lgcheng, 2016/07/29 23:53:21]

There are three main reasons for this:

1.TWO_CLIENT_LEGACY(local python server) gives me more logs while I create these
tests.
2.AwaitQuiescence() can only be used in local mock server. I need create my own
api to wait until sync finished if I use real server. But that cost extra time
while the issue is targeted to M53... Sorry 
3.It seems real server has not been ready for the new data type yet.(alpha,
integration test, prod ...) In-ho is working on server side to apply the new
datatype.

ASSERT_TRUE returns early. To ensure cleanup code is executed put it in
TearDown().

I put clearup code in TearDownOnMainThread(). Thanks for pointing out and making
the code neat and correct!
