hello-world's Introduction

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

Specification

The Hello World! program will greet me, the caller.

If I tell the program my name is Alice, it will greet me by saying "Hello, Alice!".

If I neglect to give it my name, it will greet me by saying "Hello, World!"

Test-Driven Development

As programmers mature, they eventually want to test their code.

Here we simulate Test-Driven Development (TDD), where you write your tests before writing any functionality. The simulation comes in the form of a pre-written test suite, which will signal that you have solved the problem.

It will also provide you with a safety net to explore other solutions without breaking the functionality.

A typical TDD workflow

  1. Run the test file and pick one test that's failing.
  2. Write some code to fix the test you picked.
  3. Re-run the tests to confirm the test is now passing.
  4. Repeat from step 1.
  5. Submit your solution

Instructions

Submissions are encouraged to be general, within reason. Having said that, it's also important not to over-engineer a solution.

It's important to remember that the goal is to make code as expressive and readable as we can. However, solutions to the hello-world exercise will be not be reviewed by a person, but by Travis CI, who will offer an encouraging word.
