在验证某些关键步骤时，需要截个图来记录一下当时的情况

Webdriver截图时，需要引入

importjava.io.File;importjava.io.IOException;importorg.apache.commons.io.FileUtils;importorg.openqa.selenium.OutputType;import org.openqa.selenium.TakesScreenshot;

截图方法

public static voidsnapshot(TakesScreenshot drivername, String filename)

{//this method will take screen shot ,require two parameters ,one is driver name, another is file name

String currentPath= System.getProperty("user.dir"); //get current work folder

System.out.println(currentPath);

File scrFile=drivername.getScreenshotAs(OutputType.FILE);//Now you can do whatever you need to do with it, for example copy somewhere

try{

System.out.println("save snapshot path is:"+currentPath+"/"+filename);

FileUtils.copyFile(scrFile,new File(currentPath+"\\"+filename));

}catch(IOException e) {//TODO Auto-generated catch block

System.out.println("Can't save screenshot");

e.printStackTrace();

}finally{

System.out.println("screen shot finished");

}

}

以下任务：

1.使用selenium打开百度，截图；

2.输入selenium关键字，截图；

3.搜索 并打开 selenium的百度百科，截图；

具体代码如下：

1 packagebaidu;2

在百度搜索结果中，拿到你想要的elements，可以使用浏览器的查看元素，通过xpath方法获取

运行此代码后截图效果如下：

console输出：
