nit: How about test_support_common or test_support_shared ?

Good idea, renamed to test_support_shared.

nit: I would comment here about the content dependency, since this file is so

Done.

I suspect a lot of these deps are not required. Maybe make a quick pass and see
if a couple can be eliminated? (autoclick and touch_hud seem like obvious
candidates).

This might be helpful:
cd ash/content
find . -name *test* | xargs grep include | cut --fields 2 --delimiter=" " | sort
| uniq

[sky, 2016/08/31 17:35:57]

Indeed. I just copied the list from ash_unittests. I've pruned it.
