How to Load a File for Testing with Jasmine Node?

Question

I have a simple JavaScript file, color.js, and a matching spec file, colorSpec.js.

color.js:

function Color()          


        

Answer 1

When using Jasmine Node, you'll want to export your object/function/class, in this case Color, as a node module. I like to try and make my modules work in both node or a browser, like so:

Folder Structure:

js
  - src/
      color.js
  - spec/
      colorSpec.js

src/color.js

/**
 * class Color
 *
 * @constructor
 */
function Color(red, green, blue)
{
    var current = [red, green, blue];

    this.getCurrent = function ()
    {
        return current;
    }
}

// Export node module.
if ( typeof module !== 'undefined' && module.hasOwnProperty('exports') )
{
    module.exports = Color;
}

spec/colorSpec.js

var Color = require('../src/color.js');

describe("Test the Color object", function() {
    var color = new Color(255, 255, 255);

    it('to verify that it can return a color.', function() {
        expect(color.getCurrent()).toContain(255);
    });
});
