从量角器进入工厂 [英] Access to factory from protractor

问题描述

我的应用程序中有一个小工厂( myFactory ):

Hi I have small factory (myFactory) in my application:

.factory('myFactory', ['$q',  function ($q) {

      function myMethod() {
        .....
      }

      return {
        myMethod: myMethod
      };
}]);

我想在量角器测试中访问 myFactory.myMethod()，因此在onPrepare()中，我正在使用

I want to get access to myFactory.myMethod() in protractor test so in onPrepare() I'm using

browser.executeScript(function() {
    return angular.element(document).injector().get('myFactory'); 
}).then(function (myFactory) {
    console.log('myFactory: ', myFactory);
    myFactory.myMethod();
});

对于 console.log('myFactory:'，myFactory)我看到我得到了对象:

for console.log('myFactory: ', myFactory) I see I get object:

myFactory:  { 
    myMethod: {}
}

然后 myFactory.myMethod(); 我看到错误:TypeError:对象不是函数

Then for myFactory.myMethod(); I see error: TypeError: object is not a function

任何人都知道我如何能够从量角器访问工厂并能够执行方法吗?

Anyone know how I can get access to factory from protractor to be able to execute method?

推荐答案

我使用服务通过Protractor访问我的应用程序中的用户信息，我继续并尽可能地在接近您的代码的位置进行操作，我在上面的评论应该是您的解决方案.这是更长的解释:

I use services to access user information in my app via Protractor, I went ahead and played around with this as close to your code as I could, my comment above should be your solution. Here's the longer explanation:

因此，我们有一个 Users 服务，它具有一个名为 getCurrent()的函数，该函数将检索当前用户的信息.因此，我第一次尝试使用与您相似的代码:

So we have a service Users, with a function called getCurrent() that will retrieve the information of the current user. So first time I tried code similar to yours:

browser.executeScript(function () {
    return angular.element(document.body).injector().get('Users');
}).then(function (service) {
    console.log(service); // logs object which has getCurrent() inside
    service.getCurrent(); // error, getCurrent() is not a function
});

这记录了 Users 对象，并包含了函数 getCurrent()，但是当我尝试链接调用 service时遇到了与您相同的错误.getCurrent().

This logged the Users object, and included the function getCurrent(), but I encountered the same error as you when I tried to chain the call service.getCurrent().

DID对我有用的只是将 .getCurrent()移到执行脚本中.即

What DID work for me, was simply moving the .getCurrent() into the execute script. i.e.

browser.executeScript(function () {
    return angular.element(document.body).injector().get('Users').getCurrent();
}).then(function (service) {
    console.log(service); // logs John Doe, [e-mail] etc.
});

因此，将其应用于您的案例，下面的代码应该可以工作:

So applying that to your case, the below code should work:

browser.executeScript(function() {
    return angular.element(document).injector().get('myFactory').myMethod(); 
}).then(function (myFactory) {
    console.log(myFactory); // this should be your token
});

仅是次要的FYI，您还可以通过将字符串传递给 executeScript

And just a minor FYI, for what it's worth you also could have written this code by passing in a string to executeScript:

browser.executeScript('return angular.element(document).injector().get("myFactory").myMethod()').then(function (val) {
    console.log(val);
});
