`expectations', the simplest unit test framework using `ert'. No test names! No extra typing! This is aimed for a successor of el-expectations. If you use el-expectations, you can simply replace. I love Jay Fields' expectations unit testing framework in Ruby. It provides one syntax and can define various assertions. So I created Emacs Lisp Expectations modeled after expectations in Ruby. Testing policy is same as the original expectations in Ruby. Visit expectations site in rubyforge. http://expectations.rubyforge.org/ With Emacs Lisp Mock (el-mock.el), Emacs Lisp Expectations supports mock and stub, ie. behavior based testing. You can get it from EmacsWiki http://www.emacswiki.org/cgi-bin/wiki/download/el-mock.el The biggest advantage is this uses `ert' feature to display test result. You can easily understand why a test failed. `expectations' vs `ert' (expect 10 (ert-deftest erte-test-00001 () (+ 4 6)) (should (equal 10 (+ 4 6)))) Example: (expectations (desc "success") (expect 10 (+ 4 6)) (expect 5 (length "abcde")) (desc "fail") (expect 11 (+ 4 6)) (expect 6 (length "abcde"))) Press C-M-x sexp then get the result in *ert*: Selector: t Passed: 2 Failed: 2 (2 unexpected) Total: 4/4 Started at: 2012-10-09 15:37:17+0900 Finished.

The load-path is usually ~/elisp/. It's set in your ~/.emacs like this: (add-to-list 'load-path (expand-file-name "~/elisp")) And the following to your ~/.emacs startup file. (require 'ert-expectations) No need more.
