CLUnit is a Common Lisp unit testing framework. It is designed to be easy to use so that you can quickly start testing.
CLUnit provides a rich set of features aimed at improving your unit testing experience: + Multiple inheritance for test suites allows you to group tests into hierarchies. + Composes the test results of each test run into a single report. + Allows redefinition of inline functions and macros without having to redefine your tests. + Supports composable test suite fixtures. + Allows for an interactive testing process which gives you access to the test environment. + Provides visual feeback of the unit test progress. + Extensible test reporting. Builtin support for default reporting and TAP output.
