Test suite
Solution

The classical introductory exercise. Just say "Hello, World!".

"Hello, World!" is the traditional first program for beginning programming in a new language or environment.

The objectives are simple:

  • Write a function that returns the string "Hello, World!".
  • Run the test suite and make sure that it succeeds.
  • Submit your solution and check it at the website.

If everything goes well, you will be ready to fetch your first real exercise.

Project Structure

Clojurescript Exercises in Exercism use Clojure CLI to configure and run your code and use some clojure/script dependencies to manage test process.

You will find a test file named hello_world_test.clj inside test directory. Write your code in src/hello_world.cljs. It should use the namespace hello-world so that tests can pick it up.

Running tests

Run the tests using clj -A:test command and make them pass:

$ clj -A:test

Testing hello-world-test

Ran 1 tests containing 1 assertions.
0 failures, 0 errors.

Then submit the exercise using:

$ exercism submit src/hello_world.clj

For more detailed instructions and learning resources refer Exercism's Clojurescript Language Page.

This is an exercise to introduce users to using Exercism http://en.wikipedia.org/wiki/%22Hello,_world!%22_program

Submitting Incomplete Solutions

It's possible to submit an incomplete solution so you can see how others have completed the exercise.

hello_world_test.cljs

(ns hello-world-test
  (:require hello-world
            [cljs.test :refer [deftest testing is] :include-macros true]))

(deftest test-hello-world
  (testing "Testing hello-world function..."
    (is (= (hello-world/hello-world)
             "Hello, World!"))))
(ns hello-world)

(defn hello-world []
  "Hello, World!")
