Can you add one for where the profile only has either name or phone missing, so
that it has a score of one, and one where it has only the email, so a score of
0?

Thanks!

[tmartino, 2017/04/05 21:30:29]

Done

+  // Null profile returns 0.
+  EXPECT_EQ(0, comp.GetContactCompletenessScore(nullptr));
+}

[sebsg, 2017/04/04 22:17:17]

Can you also add a test for IsContactInfoComplete? thanks!
