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；
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 stubSystem.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 stubDesiredCapabilities 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/");}}

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 stubFile 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/");}}
