How to use
|
|
----------
|
|
|
|
1. Read the documentation in lisp-unit.html.
|
|
|
|
2. Make a file of DEFINE-TEST's. See exercise-tests.lisp for many
|
|
examples. If you want, start your test file with (REMOVE-TESTS) to
|
|
clear any previously defined tests.
|
|
|
|
2. Load this file.
|
|
|
|
2. (use-package :lisp-unit)
|
|
|
|
3. Load your code file and your file of tests.
|
|
|
|
4. Test your code with (RUN-TESTS test-name1 test-name2 ...) -- no quotes! --
|
|
or simply (RUN-TESTS) to run all defined tests.
|
|
|
|
A summary of how many tests passed and failed will be printed,
|
|
with details on the failures.
|
|
|
|
Note: Nothing is compiled until RUN-TESTS is expanded. Redefining
|
|
functions or even macros does not require reloading any tests.
|
|
|
|
For more information, see lisp-unit.html.
