WaE: variable set but not used, in NDEBUG build

Seems that people prefer this to be CPPUNIT_ASSERT() instead of
assert().

My first thinking was that there is a slight difference in meaning;
that assert() checks that the code (or, in this case, data) in the
test *itself* is as expected while CPPUNIT_ASSERT() checks that the
functionality *somewhere else* works as expected. But whatever.
