# 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
|
||
|
|
$ mix test
|
||
|
|
```
|
||
|
|
|
||
|
|
### 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
|
||
|
|
```
|
||
|
|
|
||
|
|
If you're stuck on something, it may help to look at some of
|

|
|
the [available resources](https://exercism.io/tracks/elixir/resources)
|
||
|
|
out there where answers might be found.
