四、使用FirefoxDriver时报错Make sure firefox is installed问题

FirefoxDriver调用firefox浏览器的安装路径应为C盘的默认目录下，若firefox安装在其他目录下执行时会报错：
Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: XP
Build info: version: '2.25.0', revision: '17482', time: '2012-07-18 21:09:54'
System info: os.name: 'Windows XP', os.arch: 'x86', os.version: '5.1', java.version: '1.6.0_10'
这是因为找不到firefox的原因。
解决办法：
1.重新安装firefox在默认路径下；

OS	Expected Location of Firefox
Linux	firefox (found using "which")
Mac	/Applications/Firefox.app/Contents/MacOS/firefox
Windows	%PROGRAMFILES%\Mozilla Firefox\firefox.exe

2.直接用System.setProperty方法设置webdriver.firefox.bin的值

package selenium.test.googleSearch;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.*;
public class BaiduFirefoxDriver {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.setProperty("webdriver.firefox.bin", "D:\\Program Files\\Mozilla Firefox\\firefox.exe");
		WebDriver driver=new FirefoxDriver();
		driver.get("http://www.baidu.com/");
	}

}

3.利用setCapability进行设置

package selenium.test.googleSearch;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.*;
import org.openqa.selenium.remote.DesiredCapabilities;
public class BaiduFirefoxDriver {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		DesiredCapabilities capability=DesiredCapabilities.firefox();
		capability.setCapability("firefox_binary",
        "D:\\Program Files\\Mozilla Firefox\\firefox.exe");
        WebDriver driver = new FirefoxDriver(capability);
		driver.get("http://www.baidu.com/");
	}

}

4.用FirefoxBinary类和public FirefoxDriver(FirefoxBinary binary, FirefoxProfile profile)这个构造方法

package selenium.test.googleSearch;

import java.io.File;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.*;
public class BaiduFirefoxDriver {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		File pathToFirefoxBinary = new File("D:\\Program Files\\Mozilla Firefox\\firefox.exe");  
		FirefoxBinary firefoxbin = new FirefoxBinary(pathToFirefoxBinary);  
		WebDriver driver = new FirefoxDriver(firefoxbin,null);
		driver.get("http://www.baidu.com/");
	}

}
