使用Protractor访问JS范围元素/变量 [英] Accessing JS scope elements/variables with Protractor

问题描述

我有一个Protractor测试，输入登录数据并单击登录按钮，我希望检查Angular变量的值。

I have a Protractor test that enters login data and clicks the login button and I wish to check the value of an Angular variable.

ng-click for the ng clicked元素是doLogin（），它在控制器文件中定义为：

The ng-click for the clicked element is doLogin() which is defined in the controller file as:

$scope.doLogin  = function(){
        console.log('login -- todo');
        // remember email used
        localStorageService.add('lastKeyEmail', $scope.data.login.key.email);
        // todo - make dynamic
        $scope.authentication.user = true;
        // set email of logged in user
        // todo: would need to be done in user service (set user details received from server)
        Authentication.setEmail($scope.data.login.key.email);
        // overwrite password in memory
        $scope.data.login.password = "thispasswordisdeletedsoyoucantreadit";
    };

如何在$ scope.authentication.user的值上使用Protractor的expect（）？

How do I use Protractor's expect() on the value of $scope.authentication.user?

推荐答案

有一个名为 evaluate 的函数可以让你评估角度表达式给定一个元素。

There is a function called evaluate that allows you to evaluate an angular expressions given an element.

选择要检查范围的DOM元素，然后调用evaluate。文档中有一个例子：

Select a DOM element for which you want to examine the scope, then call evaluate. There is an example in the documentation:
