Don't use ASSERT in a helper function. Many developers do not immediately
understand that it returns on failure, so the fact that it _must_ be an ASSERT
(not an EXPECT) here is not self-evident.

Use two EXPECTs and an if (...) return; instead.

Done.

I believe there is also a TestingPrefService which would serve your needs at a
lower level.
