Similar to https://gist.github.com/jonnybojangles/7492609 but this snippet extends the module widget. Good for use across multiple files.

angular-extend-module-and-factory-test-example.js

angular.module('widget', []).
	factory('widgetVersion', function(){
		return {
			version: '0.123'
		}
	});
/*
* Extend widget, sans []s
* */
angular.module('widget').
	config(function($provide){
		$provide.factory('widgetDate', function(){
			return {
				date: 'Today'
			}
		});
	});
describe('Test widget', function(){
	"use strict";
	beforeEach(module('widget'));
	/*
	 * Testing a factory
	 * */
	describe('widgetVersion', function(){
		"use strict";
		it('Make sure the widget version is correct.', inject(function(widgetVersion){
			expect(widgetVersion.version).toBe('0.123');
		}));
	});

	/*
	 * Testing config (factory)
	 * */
	describe("widgetDate", function () {
		"use strict";
		it("Does the widget date match our expect value?", inject(function(widgetDate){
			expect(widgetDate.date).toBe('Today')
		}));
	});
});
