I wrote a C++ implementation of the Framework for Integrated Test (FIT) called CeeFIT, and I was really proud of the way it registered fixtures at compile time.

Anyhow, I was surprised that more than one user was using CeeFIT as a sort of batch runner for C++ code, feeding in rows tabular data and executing it against their code. There were a couple bugs I had to fix to support their use cases.

I was just happy to have users.
