Ah, I see.  I think the reason for checking config.modules is because
we need to distinguish between "module had been disabled" and "module
was enabled, but failed to load due to a bug".  That is, we want the
test suite to fail if the module failed to load even though it was
enabled in config.modules.

However, most Test/V*.ztst files use a simple «if ! zmodload zsh/foo; …»

So, I think we should write a ZTST_* helper function that encapsulates
the config.modules check, and then call it as «ZTST_load_or_skip zsh/foo || return $?»
to make sure that V${N}foo.ztst fails if «zmodload zsh/foo» unexpectedly failed.

Makes sense?
