Why is this needed? Only DISABLED_ is a valid prefix these days.

Either way, it doesn't look ppapi-specific to me.

[tommycli, 2015/04/16 22:18:51]

Done. In the latest patch, these lines are untouched.

I think it's only called within src/chrome/test/ppapi/ppapi_browsertest.cc and
src/content/test/ppapi/ppapi_browsertest.cc.

This is the same as the file I moved it from.

[Paweł Hajdan Jr., 2015/04/17 01:38:01]

Even if it's just a move, I'd like to keep content/public/test quality really
high.

There is just no such thing as FAILS_, FLAKY_, or SLOW_.

Doing any post-processing for DISABLED_ tests is suspicious but I can't stop
you. I just don't think any such logic belongs in generic test utilities.

Done.

Shouldn't this return bool so that callers can bail out early if it fails?

Done.
