"Hello, World!" is the traditional first program for beginning programming in a new language or environment.
The objectives are simple:
If everything goes well, you will be ready to fetch your first real exercise.
This is an exercise to introduce users to using Exercism http://en.wikipedia.org/wiki/%22Hello,_world!%22_program
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
;;; hello-world-test.el --- Tests for Hello World (exercism) ;;; Commentary: ;; Common test data version: 1.1.0 be3ae66 ;;; Code: (load-file "hello-world.el") (ert-deftest hello-world-test () (should (equal (hello) "Hello, World!"))) (provide 'hello-world-test) ;;; hello-world-test.el ends here

A huge amount can be learnt from reading other people’s code. This is why we wanted to give exercism users the option of making their solutions public.
Here are some questions to help you reflect on this solution and learn the most from it.
