问题描述

好吧,所以我一直对一些问题的绊脚石很长一段​​时间,我想听听来自社会其他成员的意见。

Alright, so I have been stumbling upon some issue for a long time and I would like to hear an opinion from the rest of community.

首先,让我们看看一些抽象的控制器。

First, let's look at some abstract controller.

function Ctrl($scope, anyService) {

   $scope.field = "field";
   $scope.whenClicked = function() {
      util();
   };

   function util() {
      anyService.doSmth();
   }

}

显然,我们在这里:

Clearly we have here:


  • 常规支架的控制器 $范围和一些服务性注入

  • 某些领域和附着范围功能

  • 私有方法 UTIL()

  • regular scaffold for controller with $scope and some service injected
  • some field and function attached to the scope
  • private method util()

现在,我想管这个类的单元测试(茉莉花)。然而,问题是,我要验证,当我点击(呼叫 whenClicked())的一些项目的 UTIL()方法将被调用。我不知道该怎么做,因为茉莉花测试我总是收到错误,无论是模拟的 UTIL()尚未定义或者不叫

Now, I'd like to cover this class in unit tests (Jasmine). However, the problem is that I want to verify that when I click (call whenClicked()) some item that the util() method will be called. I don't know how to do that, since in Jasmine tests I'm always getting errors that either the mock for util() hasn't been defined or was not called.

注意:我并不想解决这个特殊的例子,我问一般的测试这样的code模式。所以,请不要告诉我什么是确切的错误。我问怎么做,而不是如何解决这个问题。

我一直试图解决此许多方式:

I have been trying a number of ways around this:


  • 很明显,我不能使用 $范围在我的单元测试,因为我没有这个功能,连接到该对象(通常使用消息结束预计间谍,但得到未定义或类似)

  • 我试图通过连接到控制器对象的功能 Ctrl.util = util的; ,然后验证像嘲弄 Ctrl.util = jasmine.createSpy ()但在这种情况下, Ctrl.util 不被调用,所以测试失败

  • 我试图改变 UTIL()附加到这个对象和嘲讽 Ctrl.util 再次,没有运气

  • obviously I cannot use $scope in my unit tests as I don't have this function attached to this object (it usually ends with message Expected spy but got undefined or similar)
  • I tried attaching those functions to the controller object via Ctrl.util = util; and then verifying mocks like Ctrl.util = jasmine.createSpy() but in this case Ctrl.util is not being called so tests fail
  • I tried to change util() to be attached to this object and mocking Ctrl.util again, with no luck

好吧,我找不到我的身边就这样,我希望从JS忍者一些帮助,工作小提琴将是完美的。

Well, I cannot find my way around this, I would expect some help from JS ninjas, a working fiddle would be perfect.

推荐答案

命名空间上它的范围是污染。你想要做的是提取逻辑放到一个单独的函数,然后注入到你的控制器。即。

Namespacing it on the scope is pollution. What you want to do is extract that logic into a separate function which is then injected into your Controller. i.e.

function Ctrl($scope, util) {

   $scope.field = "field";
   $scope.whenClicked = function() {
      util();
   };
}

angular.module("foo", [])
       .service("anyService", function(...){...})
       .factory("util", function(anyService) {
              return function() {
                     anyService.doSmth();
              };
       });

现在你可以用单元测试嘲笑你的Ctrl键的以及UTIL。

Now you can unit test with mocks your Ctrl as well as "util".
