• Lisp Unit on GitHub

lisp-unit is a Common Lisp library that supports unit testing. It is an extension of the library written by Chris Riesbeck (see). There is a long history of testing packages in Lisp, usually called "regression" testers. More recent packages in Lisp and other languages have been inspired by JUnit for Java.
