selenium webdriver译文（二）:WebDriver and the Selenium-Server

译文：webdriver和selenium-server

你是否需要selenium server，这取决于你怎么用webdriver。如果你只是想用webdriver的API，你就不需要selenium-server。如果浏览器和测试用例运行在同一台机器上，而且你的测试脚本里只用到了webdriver api，你也不需要selenium-server，因为webdriver可以直接操作浏览器。

下面是需要用到selenium-server的场景：

1）使用selenium-grid，在多机器或多虚拟机上运行测试用例。

2）你想连远程机器使用它的浏览器。

3）你没有用到java bindings（例如python, C#, or Ruby），比如使用Htmlunit Driver。

注：This(Htmlunit Driver) is currently the fastest and most lightweight implementation of WebDriver. As the name suggests, this is based on HtmlUnit. HtmlUnit is a java based implementation of a WebBrowser without a GUI. For any language binding (other than java) the Selenium Server is required to use this driver.

Htmlunit Driver是当今最快最轻量级的webdriver应用。顾名思义，它是基于HtmlUnit的。HtmlUnit是一款基于无界面浏览器实现的java(这句要怎么翻啊？？)。任何绑定selenium server的语言（除了java）都需要Htmlunit Driver.

注2： HtmlUnit 是 JUnit 的扩展测试框架之一.

You may, or may not, need the Selenium Server, depending on how you intend to use Selenium-WebDriver. If you will be only using the WebDriver API you do not need the Selenium-Server.  If your browser and tests will all run on the same machine, and your tests only use the WebDriver API, then you do not need to run the Selenium-Server; WebDriver will run the browser directly.

There are some reasons though to use the Selenium-Server with Selenium-WebDriver.

• You are using Selenium-Grid to distribute your tests over multiple machines or virtual machines (VMs).
• You want to connect to a remote machine that has a particular browser version that is not on your current machine.
• You are not using the Java bindings (i.e. Python, C#, or Ruby) and would like to use HtmlUnit Driver
