在量角器测试中访问 Angular [英] Accessing Angular inside Protractor Test

问题描述

是否可以像在单元测试中那样在量角器测试中访问 angular?

Is it possible to access angular within your protractor tests like you do in unit testing?

用例是我有一个转换文本的服务，我想访问该服务以转换实际测试脚本中的一些数据.我知道量角器中有 addMockModule 方法，但我不知道如何为此目的使用它.

Use case is that I have a service that transforms text and I want to access that service to transform some data within the actual test script. I know there is the addMockModule method in protractor but I cannot figure out how to use it for this purpose.

非常感谢您的帮助！

推荐答案

有一个函数叫做evaluate().在dom中找到一个元素，然后运行表达式.

There is a function called evaluate(). Find an element in the dom and then run the expression.

例如.如果您想计算 http://angularjs.org/ 网站(在 Add Some Control 下)中的待办事项数量，请执行以下操作:

For example. If you want to count the number of todos in the http://angularjs.org/ website (under Add Some Control), do this:

在量角器中打开元素浏览器

Open the element explorer in protractor

./node_modules/protractor/bin/elementexplorer.js
browser.get('http://angularjs.org/')
element(by.model('todoText')).evaluate('todos.length').
  then(function(count) {
    console.log(count)
  });

它应该给你一个 2

您也可以使用 executeAsyncScript

You can also use executeAsyncScript

browser.executeAsyncScript(function(callback) {
  // Here we use document.body, but your app may live under a different
  // element.
  var service = angular.element(document.body)
      .injector()
      .get('myService');
  service.query({}, function(data) {
    callback(data);
  });
}).then(function (output) {
  console.log(output);
});
