Add to your ~/.emacs

(require 'el-spec)

and write some test, for example

(dont-compile
  (when (fboundp 'describe)
    (describe "description"
      (before
        (message "before common"))
      (after
        (message "after common\n"))
      (context "when 1"
        (before
          (message "before 1"))
        (after
          (message "after 1"))
        (it "test 1"
          (message "test 1")))
      (context "when 2"
        (before
          (message "before 2"))
        (after
          (message "after 2"))
        (it "test 2"
          (message "test 2")))
      )))
