ricky-ortega's solution

to Hello World in the CFML Track

Published at Apr 16 2021 · 0 comments
Instructions
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.


To run the code in this exercise, you will only need to have CommandBox CLI installed. This binary runs CFML code from the command line.

To run the tests, cd into the exercise folder and run the following:

box task run TestRunner
# Or start up a test watcher that will rerun when files change
box task run TestRunner --:watcher

The tests leverage a library called TestBox which supports xUnit and BDD style of testing. All test suites will be written in the BDD style which uses closures to define test specs. You won't need to worry about installing TestBox. The CLI test runner will take care of that for you. You just need to be connected to the internet the first time you run it. You can read more about it here:

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.

HelloWorldTest.cfc

component extends="testbox.system.BaseSpec" {

	function beforeAll(){
	  SUT = createObject( 'HelloWorld' );
	}

	function run(){
	
		describe( "My HelloWorld class", function(){			

			it( 'Say Hi!', function(){
				expect( SUT.hello() ).toBe( 'Hello, World!' );
			});

		});
		
	}
 
}

SolutionTest.cfc

component extends="HelloWorldTest" {

	function beforeAll(){
	  SUT = createObject( 'Solution' );
	}

}
/**
* Your implmentation of the Hello World exercise
*/
component {
	
	/**
	* @returns A string greeting the world
	*/
	 function hello() {
		return 'Hello, World!';
	}
	
}
