Did you forget to "git add" this file? I don't see it anymore.

(And thanks for writing a test suite! It's very helpful.)

Sorry for the silly mistake. 
ime_menu_tray_unittest.cc breaks some include rules, as it need
status_area_widget.h and aura/window.h, so I put it under ash/system/. Is that
OK?
