selenium用于页面自动化测试，其简介云云这里不再粘来粘去的赘述，浪费时间。下面说说自己遇到的一点小问题，及其处理方法。
一：selenium安装
安装方法，百度一下，相比大家都会见到很多前辈们的详细解释。但是也并不是每个都好使的。
本人使用的火狐版本是53.0.3（32），直接在插件中搜索selenium，安装了其所有插件，重启浏览器，点击selenium IDE图标，反应半天后经给我弹出窗口selenium IDE为安装！！！
selenium官网也因为墙的问题不能访问，后来参照了易百教程（http://www.yiibai.com/selenium/selenium_download_ide.html），成功安装。
打开浏览器，录制操作，重放，一切都很顺利。
二：MyEclipse中使用selenium
第一步中已经录制了简单的demo。执行导出java/JUnit4/WebDriver,得到Demo.java文件。
在MyEclipse中创建maven项目，根据需要，引入依赖junit，selenium-chrome-driver|selenium-firefox-driver(注意自己浏览器的版本)，selenium-java-client-driver。
把生成的Demo.java文件放入到项目中。处理包路径等问题。
运行。。。
哈哈，问题来了！
java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see http://code.google.com/p/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://code.google.com/p/chromedriver/downloads/list
...
根据提示，设置path：
File file = new File("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());
再次执行，哇！好感动，浏览器成功启动了！然而。。。后续的操作却没有，我们记录的访问等等都没有执行！
回到MyEclipse，发现JUnit报错：
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

上述问题几经百度未果，无奈只好硬着头皮看报错，原来是ChromeDriver无法调用。经过查阅得知ChromeDriver是selenium操作chrome的驱动器，他不存在与我们的java代码中，我们需要根据自己chrome的版本下载对应的ChromeDriver.exe,我将下载到的ChromeDriver.exe放在了chrome同级目录下。然后修改我们的代码：
File file = new File("C:\\Program Files (x86)\\Google\\Chrome\\Application\\ChromeDriver.exe");
System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());
运行，记录的访问完美执行。
