I agree with you. Most of my functions/methods have more compact
doctests (putting things on many lines has the advantage of letting
you locate the failing tests in a simpler way).

Doctests are simpler and faster to use for me, and they have the
advantage of keeping tests close to the tested things, instead of
scattering things in two or more places.
Generally between the choice of less tests or more doctests, I prefer
more doctests. If you have infinite time you don't need to take such
choices.

I did know this... Maybe the a single function can be put there, fit
for everyone.

I didn't know about this, thank you. I think the timeit docs don't
show that function well enough, I can't find it in a quick search. And
that name is quite long to write, so maybe a shorter name is better
(like "timer").

Bye and thank you,
