With [svn r12402][1], I've gotten the ABCL Lisp tests to a point that I am much happier with the interface.
Loading and running the tests via ASDF is now the preferred method, and the Ant targets now utilize this, but here are some quick notes for invoking the tests from an ABCL REPL:
I currently have overloaded the 'abcl.asd' with definitions for many subsystems, which works will if you symlink this file to 'abcl-test-lisp.asd', then
CL-USER> (asdf:operate 'asdf:load-op :abcl-test-lisp)
will load the tests.
Now you can use ASDF to run all the tests
CL-USER> (asdf:operate 'asdf:test-op :abcl-test-lisp)
or, once the tests have been loaded, there is a convenience function ABCL.TEST.LISP:RUN-MATCHING that will run a subset of the tests
CL-USER) (abcl.test.lisp:run-matching "jar-file")
will run all tests which have the string "jar-file" in their name. Reporting here isn't the best yet as this only currently reports errors, so if you get a NIL, it means all the tests you specified succeeded.
