yes, elunit 1.0!



Has it really almost been a week? Well, it's been a good week for hacks.

ElUnit is a unit testing framework for Emacs Lisp designed to allow Test-Driven development. I believe it to be pretty much at release quality, though a few more convenience macros (assert-equal, for instance) remain to be written. You define suites of tests using the defsuite macro:

(defsuite my-test-suite
    "Test that 2 + 2 = 4"
    (assert (equal 4 (+ 2 2))))

    (assert (equal 0 (- 2 2))))

    "This test should fail!"
    (assert (equal 5 (+ 2 2))))

    "duplicate should overwrite original"
    (assert (equal 3 (length (elunit-suite 'my-test-suite))))))

(add-hook 'my-test-suite-teardown-hook (lambda () (message "teardown hook")))

M-x elunit gets you some nicely formatted reports:

Loaded suite:  my-test-suite


1) Failure:  bad-math [/home/phil/.emacs.d/elunit-test.el: 13]
            This test should fail!
    Result:  (cl-assertion-failed (equal 5 (+ 2 2)))

3 tests total,  1 failures in 0 seconds.

How many times do I have to tell you that two plus two is four? Anyway, I'm pretty happy with the results, especially considering I was able to keep it at about 90 LOC. Give it a shot, and if you've got anything to say, pipe up on the wiki discussion.

Grab it straight out of my Trac.
