Lisp Unit

CMUCL uses ​Lisp-Unit for unit testing.

The test suite should be run before a snapshot is tagged and released.

To run the test suite:

1. You must be in the top of the CMUCL source tree.
2. If you have not installed CMUCL, you must install it.
   1. Run bin/make-dist.sh -I <dir> to install it.
3. For the full test suite, run <lisp> -noinit -load tests/run-tests.lisp -eval '(cmucl-test-runner:run-all-tests)'
4. To run just one of the test suites:
   1. Run lisp
   2. (require :lisp-unit)
   3. Load one of the files in tests
   4. Run the test using (lisp-unit:run-tests :all <package>).
      1. The package name is the file name appended with "-TESTS". For example, the trig tests are in trig.lisp and the package name is "TRIG-TESTS".
