量角器 - 在哪里使用 browser.waitForAngular()
我有一些使用量角器为 angular.js 应用程序编写的测试.我正在使用 Page Objects 设计模式，并且我有一些方法可以通过单击链接和按钮导航到其他页面.不久之后，我正在调用 browser.waitForAngular().
I have some tests written using protractor for angular.js app. I am using Page Objects design pattern and there i have some methods that navigate to other pages by clicking on links and buttons. and soon after that i am calling browser.waitForAngular().
页面对象
module.exports = function () {
this.companyNameLink = element(by.id('viewCompany'));
this.newMeetingButton = element(by.id('newMeetingButton'));
this.createNewGeneralMeeting = function () {
this.newMeetingButton.click();
browser.waitForAngular();
};
this.goToCompanyPage = function () {
this.companyNameLink.click();
browser.waitForAngular();
};
};
在一些规范文件中，我像这样使用这个页面对象..
And in some spec file i use this page object like this..
var DashboardPage = require('../dashboardPageObject.js');
dashboardPage = new DashboardPage();
...
dashboardPage.goToCompanyPage();
但问题是有时我得到 angular could not be found on the window 错误并且我的测试失败.大多数时候测试运行.这个问题是随机的.我的问题是我应该从页面对象方法中删除 browser.waitForAngular() 并在我像这样调用方法后调用它...
But the problem is sometimes i get the angular could not be found on the window error and my tests fail. Most of the time the tests run. This issue is random. My question is that should i remove the browser.waitForAngular() from the page object method and call it after i make the method call like this...
修改后的页面对象
...
this.goToCompanyPage = function () {
this.companyNameLink.click();
};
...
规格文件
dashboardPage.goToCompanyPage();
browser.waitForAngular();
调用 browser.waitForAngular() 是否会导致问题?我应该在哪里调用 waitForAngular 有没有关于如何使用它的最佳实践?
Is calling browser.waitForAngular() causing the issue? Where should i call waitForAngular is there any best practice on how to use this?
推荐答案
来自protractor的文档:
From protractor's documentation:
指示 webdriver 等到 Angular 完成渲染并且没有未完成的 $http 或 $timeout 调用后再继续.请注意，量角器会在每个 WebDriver 操作之前自动应用此命令.
Instruct webdriver to wait until Angular has finished rendering and has no outstanding $http or $timeout calls before continuing. Note that Protractor automatically applies this command before every WebDriver action.
你根本不应该调用这个，我想不出一个你应该调用的有效案例.
You shouldn't be calling this at all and I cannot think of a valid case where you should.
