本文介绍了一个使用Selenium WebDriver与Firefox浏览器进行网页自动化测试的例子。通过创建一个简单的Java程序，演示了如何打开百度网站，输入搜索关键词并触发搜索，同时记录操作过程中的关键信息。

基于Eclipse Java EE IDE for Web Developers.
Version: Mars.2 Release (4.5.2)

新建test4.java

package ST;

import org.openqa.selenium.*;
import org.openqa.selenium.WebDriver.*;
import org.openqa.selenium.firefox.*;

public class test4 {
    public static void main(String[] args)
    {
        WebDriver driver = new FirefoxDriver();
        org.openqa.selenium.support.events.EventFiringWebDriver
        eventDriver = new org.openqa.selenium.support.events.EventFiringWebDriver(driver);
        //注册事件
        eventDriver.register(new MyWebDriverListener());
        
        //打开百度页面，输入selenium，点击搜索
        eventDriver.navigate().to("http://www.baidu.com");
        eventDriver.findElement(By.id("kw")).sendKeys("selenium");
        eventDriver.findElement(By.id("su")).click();
        
        //写一个异常
        try{
            eventDriver.findElement(By.id("XXXX"));
        }catch(Exception e){}
    }
}

新建 MyWebDriverListener .java 文件

package ST;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.events.WebDriverEventListener;

public class MyWebDriverListener implements WebDriverEventListener{

	@Override
	public void afterChangeValueOf(WebElement arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		System.out.println("更改 后的值为"+arg0.getAttribute("value"));
		
		
	}

	@Override
	public void afterClickOn(WebElement arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		try{
			Thread.sleep(4000);
		}catch(InterruptedException e){
			e.printStackTrace();
		}
		
		System.out.println("单击的页面元素后的URL为：" + arg1.getCurrentUrl() );
	}

	@Override
	public void afterFindBy(By arg0, WebElement arg1, WebDriver arg2) {
		// TODO Auto-generated method stub
		System.out.println("找到元素，其条件为"+arg0.toString());
		
	}

	@Override
	public void afterNavigateBack(WebDriver arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void afterNavigateForward(WebDriver arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void afterNavigateRefresh(WebDriver arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void afterNavigateTo(String arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		System.out.println("页面发生跳转后的URL为："+arg1.getCurrentUrl());
		
	}

	@Override
	public void afterScript(String arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void beforeChangeValueOf(WebElement arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		System.out.println("更改前的值为："+arg0.getAttribute("value"));
		
	}

	@Override
	public void beforeClickOn(WebElement arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		System.out.println("要单击的页面元素为:" + arg0.getAttribute("value"));
		
	}

	@Override
	public void beforeFindBy(By arg0, WebElement arg1, WebDriver arg2) {
		// TODO Auto-generated method stub
		System.out.println("查找元素时的条件为："+arg0.toString());
		
	}

	@Override
	public void beforeNavigateBack(WebDriver arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void beforeNavigateForward(WebDriver arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void beforeNavigateRefresh(WebDriver arg0) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void beforeNavigateTo(String arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		System.out.println("页面发生跳转前的URL为："+arg1.getCurrentUrl());
	}

	@Override
	public void beforeScript(String arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		
	}

	@Override
	public void onException(Throwable arg0, WebDriver arg1) {
		// TODO Auto-generated method stub
		java.util.Date currentTime = new java.util.Date();
		java.text.SimpleDateFormat  formatter = new java.text.SimpleDateFormat("yyyy_MM_dd_hh_mm_ss");
		String dateString = formatter.format(currentTime);
		java.io.File scrFile = ((org.openqa.selenium.TakesScreenshot)arg1).getScreenshotAs(org.openqa.selenium.OutputType.FILE);
		try{
			java.io.File screenshot = new java.io.File("D:\\"+dateString+".png");
			org.apache.commons.io.FileUtils.copyFile(scrFile,screenshot);
		}catch(java.io.IOException e){
			e.printStackTrace();		
		}
		System.out.println("Error:" + arg0.getMessage());
		System.out.println("Picture in："+ "D:\\"+dateString+".png");
		}
