I despise brevity in tests, so my strong preference is to use some form
of 'namespaced' helper. Perhaps others have better memory than
I do, but I'm quick to forget the selftests library and find the more
verbose / obvious function names helpful for jogging my memory.

Ooo, don't leave me out on the bikeshedding! How about TEST_MALLOC() /
TEST_CALLOC(). It is vaguely similar to TEST_ASSERT(), which I'd hope
would give the impression that an assertion is lurking below.
