You set up a test message in several places, it would be easier to read with a
helper function (also, sms leaks) e.g.:

base::unique_ptr<DictionaryValue> sms = CreateMessage(kDefaultNumber,
kDefaultMessage, kDefaultTimestamp);

You are right, a helper function would save many line.

[stevenjb, 2017/02/07 22:30:25]

Use ASSERT_TRUE(false) instead of NOTREACHED in tests. (NOTREACHED crashes in
debug test runs only, making the failure difficult to identify).

Good to know. Updated.
