优点：HtmlUnitDriver不会实际打开浏览器，运行速度很快。对于用FireFox等浏览器来做测试的自动化测试用例，运行速度通常很慢，HtmlUnitDriver无疑是可以很好地解决这个问题。  
缺点：它对JavaScript的支持不够好，当页面上有复杂JavaScript时，经常会捕获不到页面元素。  
\[b\]1.使用HtmlUnitDriver访问百度，并返回页面标题信息\[/b\]

package selenium.test.googleSearch;
    
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.htmlunit.HtmlUnitDriver;
    
    public class BaiduHtmlUnitDriver {
       
    
    	/**
    	 * @param args
    	 */
    	public static void main(String[] args) {
       
    		// TODO Auto-generated method stub
    		WebDriver driver=new HtmlUnitDriver();
    		//打开百度首页
    		driver.get("http://www.baidu.com/");
    		//打印页面标题
    		System.out.println("页面标题："+driver.getTitle());
    		//根据id获取页面元素输入框
    		WebElement search=driver.findElement(By.id("kw"));
    		//在id=“kw”的输入框输入“selenium”
    		search.sendKeys("selenium");
    		//根据id获取提交按钮
    		WebElement submit=driver.findElement(By.id("su"));
    		//点击按钮查询
    		submit.click();
    		//打印当前页面标题
    	    System.out.println("页面标题："+driver.getTitle());
    	    //返回当前页面的url
    	    System.out.println("页面url："+driver.getCurrentUrl());
    	    //返回当前的浏览器的窗口句柄
    	    System.out.println("窗口句柄："+driver.getWindowHandle());
    
    	}
    
    }

\[b\]2.selenium官网wiki中关于HtmlUnitDriver的例子\[/b\]

package org.openqa.selenium.example;
    
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.htmlunit.HtmlUnitDriver;
    
    public class Example  {
       
        public static void main(String[] args) {
       
            // Create a new instance of the html unit driver
            // Notice that the remainder of the code relies on the interface, 
            // not the implementation.
            WebDriver driver = new HtmlUnitDriver();
    
            // And now use this to visit Google
            driver.get("http://www.google.com");
    
            // Find the text input element by its name
            WebElement element = driver.findElement(By.name("q"));
    
            // Enter something to search for
            element.sendKeys("Cheese!");
    
            // Now submit the form. WebDriver will find the form for us from the element
            element.submit();
    
            // Check the title of the page
            System.out.println("Page title is: " + driver.getTitle());
        }
    }
