AngularJS - Jasmine -无法在控制器回调函数中测试服务

// 假设我们已经注入了userService和$controller
it('should call userService.getUser', function() {
  spyOn(userService, 'getUser');
  
  var controller = $controller('MyController');
  // 在控制器回调函数中调用userService.getUser
  controller.callback();
  
  expect(userService.getUser).toHaveBeenCalled();
});

// 假设我们已经注入了$controller
it('should call userService.getUser', function() {
  var userServiceMock = jasmine.createSpyObj('userService', ['getUser']);
  var controller = $controller('MyController', {
    userService: userServiceMock
  });
  
  // 在控制器回调函数中调用userService.getUser
  controller.callback();
  
  expect(userServiceMock.getUser).toHaveBeenCalled();
});
