Drive by: Should these be ASSERT_TRUEs instead? 

The difference is that ASSERT_TRUE will (gracefully) fail the test if the
assertion fails - which is useful for checking for NULL pointers before you
dereference them (which would crash the test and abort running more)

Yes they should. Updating now.
