selenium web driver 实现截图功能

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;

 15 import org.openqa.selenium.WebDriver;

 27   public static void snapshot(TakesScreenshot drivername, String filename)
 28   {
 29       // this method will take screen shot ,require two parameters ,one is driver name, another is file name
 30       
 31       
 32     File scrFile = drivername.getScreenshotAs(OutputType.FILE);
 33         // Now you can do whatever you need to do with it, for example copy somewhere
 34         try {
 35             System.out.println("save snapshot path is:E:/"+filename);
 36             FileUtils.copyFile(scrFile, new File("E:\\"+filename));
 37         } catch (IOException e) {
 38             // TODO Auto-generated catch block
 39             System.out.println("Can't save screenshot");
 40             e.printStackTrace();
 41         } 
 42         finally
 43         {
 44             System.out.println("screen shot finished");
 45         }
 46   }

 48     public static void main (String [] args) throws InterruptedException
 49     {

 51      
 52         String URL="http://www.baidu.com";
 53         System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe"); 
 54         WebDriver driver = new ChromeDriver();
 55         driver.get(URL);
 56         //max size the browser
 57         driver.manage().window().maximize(); 
 58  /*
 59         Navigation navigation = driver.navigate();
 60          navigation.to(URL);*/
 61          Thread.sleep(2000);
 62          snapshot((TakesScreenshot)driver,"open_baidu.png");
 63          //WebElement reg=driver.findElement(By.name("tj_reg"));
 64          //reg.click();
 65          //    WebElement keyWord = driver.findElement(By.id("kw1"));

 74          
 75  
 76          
 77           WebElement submit = driver.findElement(By.id("su1"));
 78           
 79           System.out.println(submit.getLocation());
 80           submit.click();
 81           //System.out.println(driver.getWindowHandle());
 82          Thread.sleep(5000);
 83           
 84         // System.out.println(driver.getPageSource());
 85         
 86         String pageSource=driver.getPageSource();
 87        //  System.out.println(pageSource);
 88         //WebElement link =driver.findElement(By.xpath(SELENIUM_LINK));
 89         WebElement link =driver.findElement(By.xpath("//*[@id=\"1\"]/h3/a"));     //*[@id="1"]/h3/a
 90         link.click();
 91         Thread.sleep(5000); 
 92         driver.switchTo().window(driver.getWindowHandles().toArray(new String[0])[1]);
 93

 95         System.out.println(driver.getTitle());
 96          Thread.sleep(5000);
 97     //     navigation.back();
 98           snapshot((TakesScreenshot)driver,"open_bake.png");
 99          System.out.println(driver.getTitle()+"\n"+driver.getCurrentUrl());
100          
101      
102          
103           driver.quit();
104            
105        
106     }
107     
108 }

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：
