The most up-to-date view on the state of all things ASDF-installable (i.e., which libraries work on which Lisps) is at https://common-lisp.net/project/cl-containers/asdf-status/website/output/ (but note with disappointment that it's more than a decade out of date).
This test tool is another one of Gary King's projects.
- ASDF-Install-Tester requires Trivial-HTTP. That is currently not ASDF-Installable so you'll need to get it via subversion. See its page for details.
- ASDF-Install-tester currently works under OpenMCL, SBCL and Allegro on OS X, and SBCL on linux x86.
- Inspiration for this comes in part from Alan Shields' cl-smoketest.
- When all is well with (some portion of) the world, ASDF-status will be able to display ASDF-Install-tester)'s results.
