This time we’ll take a look at how to write better tests in the form of harness programs (also known as fuzz drivers, programs are written to exercise specific parts of the code) that we will use for fuzz testing. If we want to improve our confidence, we can add steps to exercise more of the code.

Tech pundits still seem to commonly assume that UB is so fundamentally entangled in C++s specification and programs that C++ will never be able to address enough UB to really matter. Background in a nutshell: In C++, code that (usually accidentally) exercises UB is the primary root cause of our memory safety and security vulnerability issues.

The unstated assumption behind this discussion is that, if we don’t reduce the workforce as routine tasks get taken over by machines, we need to re-skill them so that they can move into other parts of the institution and perform a different set of tightly specified and highly standardized tasks.

This can be changed later using the pg_checksums utility, but that will be a painful exercise on a big database.
