如何指定在Java中使用Selenium lib時要模擬哪個瀏覽器？

我的網頁只能在IE中使用，因爲它在javascript中使用ActiveXObject。編寫內部工具測試此網頁時，如何指定瀏覽器類型和版本？如何指定在Java中使用Selenium lib時要模擬哪個瀏覽器？

Java的代碼是：

package main; 
 

 
import java.util.concurrent.TimeUnit; 
 

 
import org.openqa.selenium.By; 
 
import org.openqa.selenium.WebDriver; 
 
import org.openqa.selenium.htmlunit.HtmlUnitDriver; 
 

 
public class Temp { 
 
    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 my web page 
 
     driver.get("http://www.test.com:8000"); 
 
     
 
     // Find the text input element by its id 
 
     driver.findElement(By.id("test")).click(); 
 
     driver.manage().timeouts().implicitlyWait(300,TimeUnit.SECONDS); 
 

 
     // Check the title of the page 
 
     System.out.println("Result is: " + driver.findElement(By.id("demo")).getText()); 
 
     driver.quit(); 
 
    } 
 
}

該網頁是：

<html> 
 
<body> 
 
<script> 
 
     function test() {  
 
\t \t try { 
 
\t \t var variable_name; 
 
\t \t \t variable_name=new ActiveXObject("Microsoft.XMLHTTP"); 
 
\t \t \t document.getElementById("demo").innerHTML = "ActiveXObject is created"; 
 
\t \t } 
 
\t \t catch(err) { 
 
\t \t \t document.getElementById("demo").innerHTML = err.message; 
 
\t \t } 
 
     } 
 
    </script> 
 
<input type="Button" id="test" value="Test" onClick='test()'> 
 
<div id = "demo">blah</div> 
 
</body> 
 
</html>
