下面是“创建AngularJS服务”一章中“依赖”例子里的“notify”服务的单元测试。测试用使用了Jasmine spy替代了真实浏览器的alert。formatDate

var mock, notify;

beforeEach(function() {
  mock = {alert: jasmine.createSpy()};

  module(function($provide) {
    $provide.value('$window', mock);
  });

  inject(function($injector) {
    notify = $injector.get('notify');
  });
});

it('should not alert first two notifications', function() {
  notify('one');
  notify('two');

  expect(mock.alert).not.toHaveBeenCalled();
});

it('should alert all after third notification', function() {
  notify('one');
  notify('two');
  notify('three');

  expect(mock.alert).toHaveBeenCalledWith("one\ntwo\nthree");
});

it('should clear messages after alert', function() {
  notify('one');
  notify('two');
  notify('third');
  notify('more');
  notify('two');
  notify('third');

  expect(mock.alert.callCount).toEqual(2);
  expect(mock.alert.mostRecentCall.args).toEqual(["more\ntwo\nthird"]);
