Anything with the attributes you could test?

Always the same problem... The faviconView is an intelligent view, not exposing
directly its image. I don't see a way to test it.

[lpromero, 2017/04/07 15:16:12]

The test you added is perfectly fine.
For testing the favicon, maybe we should do screenshot testing (not the scope of
this CL).

+  ASSERT_TRUE([title isEqualToString:tile.accessibilityLabel]);

Nit: New line.

[gambard, 2017/04/07 14:47:22]

Done.
