I'd recommend testing on as many as you can get hold on, and as
old and new systems as you still aim to support, and with as many
and as diverse compilers and toolchains as you can afford.
FWIW, I do most autotools development on GNU/Linux and then test
specific code pieces on known-problematic systems; the Autoconf
and Gnulib manuals can provide good hints here. Before a release,
I try to regression-test everywhere.
A corollary of this is that your package should easily be testable
and testing should expose as many features as possible.

Well, if one of your users overrides LC_COLLATE with LC_ALL, then it
may not be sufficient.

On my system `info find' is sufficient. You might need `info findutils'
instead, I guess, if the former brings up the man page.
