selenium web driver 实现截图功能【转】

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

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

截图方法

public static void snapshot(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 package baidu;

102
103           driver.quit();
104

106     }

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

console输出：
