Quick demo on testing angular provider

test.js

describe('Forms module', function () {
    var services;

    beforeEach(module('app', function(getHtmlProvider){
        // set service as the provider to be able to access the setters
        services = getHtmlProvider;
    }));


    // can still test the service by injecting it
    it('should return an object', inject(function (getHtml) {
        expect(typeof getHtml.get('email.remote')).toBe('object');
    }));


    // test the service setters
    it('should be modifiable', inject(function (getHtml) {
        var messages = {
            name: {
                required: 'hello world'
            }
        };
        services.setMessages(messages);
        expect(getHtml.get('name.required').name.required).toBe('hello world');
    }));
});
