In a wikitech-l thread, it was suggested that pywikibots test suite should be regularly run (on WMF infrastructure) against changes which will be deployed to Wikimedia production wikis. i.e. as part of the MediaWiki/Wikimedia CI.
A separate task (T100796) exists for running the pywikibot test suite against Wikimedia beta wikis using Travis-CI as part of the pywikibot CI. The blockers for that task are not exactly the same, but are similar. e.g. the account 'Pywikibot-test' does not need to be used by Wikimedia CI - it is an artefact of the Travis CI/GitHub system.
Running these tests will hopefully assist with T108322: prevent modules with broken paraminfo being deployed to production wikis.
Test framework is running at https://integration.wikimedia.org/ci/job/pywikibot-tests-beta-cluster/ ; however 0 tests are run due to a tox problem.
tl;dr: Test Pywikibot regularly against MediaWiki upcoming changes using Wikimedia-CI
