javascript - Angular Jasmine - 模拟服务(angularjs-rails-resource) - TypeError : object is not a function

Question

这是带有 Angular-rails gem 和 jasmine gem 的 Rails 4.0 应用程序。我还使用 angularjs-rails-resource。

我有简单的 Controller :

app.controller('new', function ($scope, Appointment, flash) {

$scope.appointment = new Appointment();
$scope.attachments = [];
$scope.appointment.agendas_attributes = [];

$scope.createAppointment = function(){

    $scope.appointment.attachments = $scope.attachments;

    $scope.appointment.create().then(function(data){
      flash(data.message);
    }, function(error){
      flash('error', error.data.message);
      $scope.appointment.$errors = error.data.errors;
    });

};

在 Jasmine 的单元测试中，我想隔离与 jasmine.createSpyObj 的依赖关系:

describe("Appointment new controller",function() {
var $scope, controller, mockAppointment, mockFlash, newCtrl;


beforeEach(function() {

    module("appointments");

    inject(function(_$rootScope_, $controller) {
      $scope = _$rootScope_.$new();

      $controller("new", {
        $scope: $scope,
        Appointment: jasmine.createSpyObj("Appointment", ["create"])
      });

    });

  });
});

但我收到错误:

TypeError: object is not a function

上线:

Appointment: jasmine.createSpyObj("Appointment", ["create"])

有人可以帮忙吗？ :-)

Answer 1

我相信错误是在这一行抛出的:

$scope.appointment = new Appointment();

Appointment 是一个对象文字，而不是一个函数，因此本质上您正在尝试执行此操作:

var x = {create: function(){}};
var y = new x();

但你似乎想做的是这样的:

var x = function(){return  {create: function(){}}};
var y = new x();

所以让你的模拟像这样:

Appointment: function() {
    return jasmine.createSpyObj("Appointment", ["create"])
}
