you're mentioning aura, but this can also be called on mac if someone set it to
true...

perhaps take out the aura bit, and just say that if it's true, the
renderviewhost object isn't a test one?

Done. I renamed the flag to is_real_render_view_host_

+  CONTENT_EXPORT static bool allow_host_view_cast_in_test_;
+
   DISALLOW_COPY_AND_ASSIGN(RenderViewHostFactory);
 };
