Page Object

Selenium？

Selenium 太慢！

WebDriver

Web自动化测试类库 �

Selenium WebDriver

•  不再是运行于浏览器的JavaScript程序 �

•  独立控制浏览器 �

•  提供了更广泛易用的API

•  提供非图形化的测试运行方式 �

•  PageFactory

快！ �

独立于浏览器 �

速度快 �

可模拟Selenium

不支持全部浏览器 �

不支持JS弹出窗口

不支持CSS Locator

I’m WebDriver

Selenium 2.0 将支持 WebDriver

Why are the projects merging? Partly because WebDriver addresses some shortcomings in selenium (by being able to bypass the JS sandbox, for example. And we’ve got a gorgeous API), partly because selenium addresses some shortcomings in WebDriver (such as suppor'ng a broader range of browsers) and partly because the main selenium contributors and I felt that it was the best way to offer users the best possible framework.
