No, indeed.  It does mostly work to test the syntax-ppss behavior, tho,
because a bug in it will typically cause bugs in indentation as well.
IOW it does largely test syntax-table and syntax-propertize, but it
doesn't test the font-lock-keywords part.

We could potentially test it by calling htmlfontify-buffer.

No, I just do something like

     make ruby.rb.test EMACS="emacs -Q --eval '(setq ruby-use-smie t)'"

Indeed, that's a widespread limitation with the current system.
