I'll look at this, this might be useful.
- compare whitespace-agnostic tests using “diff -w” or “diff -b”?
There are a couple of functions in test-glue-functions that can do this where needed.

Could tests that depend on system facilities or build options be disabled,
or have the warnings hidden when they should not be applicable:
- non-unicode locales are becoming less common, so in run-intl, exclude
the 400-odd tests that depend on non-unicode multibyte encodings, or limit> tests to those that are compatible with $LANG from the build user?
(I don't
have a terminal that can display BIG5 or SJIS, and even Latin-1 is awkward.)
Your experience is not universal; those encodings are still used. There is already code in there that warns about and skips tests if the environment doesn't have some of the more esoteric locales.
conversely:
- don't warn about needing arrays unless bash is configured without
support for arrays
- don't warn about needing process substitutions unless bash is
configured without support for process substitutions or is being tested on
a system that lacks ‘/dev/fd’ or equivalent;
- don't warn about needing BASH_ARGV unless bash is configured without
support for debugging
I'm prepared to submit patches to implement these if you could give me some
guidance on which of them you would accept (or not).
How would you implement tests for the missing features? Let's start there.
