# Hello World The classical introductory exercise. Just say "Hello, World!". ["Hello, World!"](http://en.wikipedia.org/wiki/%22Hello,_world!%22_program) 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. ## Running tests Execute the tests with: ```bash $ elixir hello_world_test.exs ``` ### Pending tests In the test suites, all but the first test have been skipped. Once you get a test passing, you can unskip the next one by commenting out the relevant `@tag :pending` with a `#` symbol. For example: ```elixir # @tag :pending test "shouting" do assert Bob.hey("WATCH OUT!") == "Whoa, chill out!" end ``` Or, you can enable all the tests by commenting out the `ExUnit.configure` line in the test suite. ```elixir # ExUnit.configure exclude: :pending, trace: true ``` For more detailed information about the Elixir track, please see the [help page](http://exercism.io/languages/elixir). ## Source This is an exercise to introduce users to using Exercism [http://en.wikipedia.org/wiki/%22Hello,_world!%22_program](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.
