I'd strongly suggest taking a look over l3build before anyone expends
effort in scripting something new. Whilst it's about more than just
testing, the core idea goes back a long way (see
As detailed in
does log-based testing with Lua doing the 'grind' and uses system
utilities for the diff step (if required). (The team and so l3build
needs to work cross-platform, so this works on *nix and Windows.) As
Norbert has noted, we've recently added PDF-based comparisons as this
will be potentially-useful for cases where log-based methods are not so
I'd also point to the automated testing we've set up:
https://travis-ci.org/latex3/latex3. (Travis-CI is one of many choices,
this is just a convenient way of running the tests on a VM we don't have
to maintain.) In amongst our own tests there are a small number for
third-party code (https://github.com/latex3/latex3/tree/master/contrib).
I talked about this at the UK-TUG meeting last year:
