# 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.
|
|
|
|
## Project Structure
|
|
|
|
* `src` contains your solution to the exercise
|
|
* `spec` contains the tests to run for the exercise
|
|
|
|
## Running Tests
|
|
|
|
If you're in the right directory (i.e. the one containing `src` and `spec`), you can run the tests for that exercise by running `crystal spec`:
|
|
|
|
```bash
|
|
$ pwd
|
|
/Users/johndoe/Code/exercism/crystal/hello-world
|
|
|
|
$ ls
|
|
GETTING_STARTED.md README.md spec src
|
|
|
|
$ crystal spec
|
|
```
|
|
|
|
This will run all of the test files in the `spec` directory.
|
|
|
|
In each test file, all but the first test have been skipped.
|
|
|
|
Once you get a test passing, you can unskip the next one by changing `pending` to `it`.
|
|
|
|
## Submitting Your Solution
|
|
|
|
Be sure to submit the source file in the `src` directory when submitting your solution:
|
|
|
|
```bash
|
|
$ exercism submit src/hello_world.cr
|
|
```
|
|
|
|
|
|
## Setup
|
|
|
|
Follow the setup instructions for Crystal here:
|

|
|
|
|
## Making the Test Suit Pass
|
|
|
|
Execute the tests with:
|
|
|
|
```bash
|
|
$ crystal spec
|
|
```
|
|
|
|
In each test suite all but the first test have been skipped.
|
|
|
|
Once you get a test passing, you can unskip the next one by changing `pending` to `it`.
