This doesn't look right. This is not printing/.

[jzfeng, 2017/05/02 07:50:56]

Done. For some reason, I added this for unittest. But now it is not needed.

I think you just want to add your test to headless_unittests. You shouldn't have
to create a new binary, and configure buildbots to run the new binary, etc.
