not necessary. //base/test:run_all_unittests pulls in gtest.

Does Chromium not advise following same IWYU rules for deps?

[alokp, 2015/06/15 18:14:39]

I dont think it spells it out as it does for header files. Including all deps
may also be unwieldy and hard to maintain IMO.

[slan, 2015/06/16 14:57:49]

Since there seems to be no prevailing pattern in Chromium, and this pattern
matches the rest of the Chromecast internal and external code, let's keep this
for now, leaning towards explicitly including every building each dependency in
build files (IWYU)
