Page Action类型的Google Chrome浏览器扩展程序,通常也会有一个图标,但这个图标位于Chrome浏览器的地址栏内右端.而且这个图标并非始终出现,而是当某指定的页面打开时才会出现.也就是说,这个图标与当前打开的页面有关,只有打开了指定的页面才会显示该图标,对该页面执行对应的操作. 定义Page Action类型的Google Chrome扩展程序,首先要在manifest.json文件中注册如下: {         ...         "page_action"

Selenium是一个用于Web应用程序测试的工具.Selenium测试直接运行在浏览器中,就像真正的用户在操作一样,可以用其进行网页动态渲染页面的爬取. 支持的浏览器包括IE(7, 8, 9, 10, 11),Mozilla Firefox,Safari,Google Chrome,Opera等. 1. 示例 ### selenium的使用 ''' Selenium是一个用于Web应用程序测试的工具. Selenium测试直接运行在浏览器中,就像真正的用户在操作一样. 支持的浏览器包括IE(7

1.document.hidden ,<高级三>中详细解释 25.2 Page Visibility API不知道用户是不是正在与页面交互,这是困扰广大Web 开发人员的一个主要问题.如果页面最小化了或者隐藏在了其他标签页后面,那么有些功能是可以停下来的,比如轮询服务器或者某些动画效果.而Page Visibility API(页面可见性API)就是为了让开发人员知道页面是否对用户可见而推出的.这个API 本身非常简单,由以下三部分组成. document.hidden:表示页面是否隐藏的布

使用python自带的unittest测试框架,用例继承自unittest.TestCase类. 1 引入接口类和页面类 2 setUp函数中打开页面,定义接口对象 3 tearDown函数中关闭页面 4 test打头的函数都是用例.因页面和接口的相关方法都已封装好,所以用例会比较简洁. 5 当一个用例需根据参数不同执行多次时,可使用ddt数据驱动,或unittest自带的subTest. # coding:utf-8 """ 页面2的测试用例 ""&qu
