I would like this to be more clearly about documenting what is
happening, as it looks from casual glance to be commented-out code one
wonders what it does here.

I would avoid the use of the back-ticks ` characters. Historically,
they can cause problems in *nix systems.

suggest you use strncpy.

since you are repeating this logic many times, you might consider
writing a helper function to count the records in the db. It will make
the test easier to read too.

these are not necessary print statements then. you can just make it a
comment somewhere in here that those functions are tested already.
