[cfe-dev] Test coverage

[AlisdairM(public)]

Looking at the test coverage results, I think we are getting lower numbers
than might be expected as assertions show up as branches not taken.  By
their nature, most of those assertions should be impossible branches!  So
should we be running the test-coverage tests with assertions disabled?

If this is already the case then I'm going to have to learn to read the
output better!
