Java selenium截图操作的实现

方法一：Selenium中截图类TakeScreenshout，这个类主要是获取浏览器窗体内的内容，不包括浏览器的菜单和桌面的任务栏区域，我们用百度首页来截图，看看截图效果。

FileUtils.copyFile(srcFile, new File("屏幕截图", time + ".png"));“屏幕截图”是我们自己创建的文件夹用来存放截图文件，此文件夹在project（工程）的更目录

；

当然也是可以设置保存到其他目录下：FileUtils.copyFile(srcFile, new File("D:\资料图片", time + ".png"));

示例代码如下：

package com.sandy;
 
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Calendar;
 
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
 
public class ScreenShot {
 
	private static WebDriver driver;
	public static void main(String[] args) throws Exception {
 
		System.setProperty("webdriver.chrome.driver", "E:\eclipse_jar\selenium_jar\chromedriver.exe");
		driver = new ChromeDriver();
		driver.get("http://www.baidu.com");
		driver.manage().window().maximize();
		
		
		SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMddHHmmss"); //转换时间格式
		String time = dateFormat.format(Calendar.getInstance().getTime()); //获取当前时间
		File srcFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); //执行屏幕截取
		FileUtils.copyFile(srcFile, new File("屏幕截图", time + ".png")); //利用FileUtils工具类的copyFile()方法保存getScreenshotAs()返回的文件;"屏幕截图"即时保存截图的文件夹
		Thread.sleep(2000);
		driver.quit();
		
	}
 
}

方法二：Robot截屏

示例代码：（示例中的图片是保存再该工程的根目录下）

package com.sandy;
 
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Calendar;
 
import javax.imageio.ImageIO;
 
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.By;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.Point;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.internal.WrapsDriver;
 
public class ScreenShot {
 
	private static WebDriver driver;
	public static void main(String[] args) throws Exception {
 
		System.setProperty("webdriver.chrome.driver", "E:\eclipse_jar\selenium_jar\chromedriver.exe");
		driver = new ChromeDriver();
		driver.get("http://www.baidu.com");
		driver.manage().window().maximize();
		robotSnapshot();
		
		Thread.sleep(2000);
		driver.quit();
		
	}
	
	
	public static void robotSnapshot() throws Exception {
		//调用截图方法
		BufferedImage img = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
		ImageIO.write(img, "png", new File("robot_screen01.png"));
	}

方法三：在测试的过程中，有时候不需要截取整个屏幕，只需要截取某个元素（或者目标区域）的图片

示例代码：

package com.sandy;
 
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Calendar;
 
import javax.imageio.ImageIO;
 
import org.apache.commons.io.FileUtils;
import org.openqa.selenium.By;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.Point;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.internal.WrapsDriver;
 
public class ScreenShot {
 
	private static WebDriver driver;
	public static void main(String[] args) throws Exception {
 
		System.setProperty("webdriver.chrome.driver", "E:\eclipse_jar\selenium_jar\chromedriver.exe");
		driver = new ChromeDriver();
		driver.get("http://www.baidu.com");
		driver.manage().window().maximize();
		
		WebElement element = driver.findElement(By.id("su"));
		elementSnapshot(element);
		//System.currentTimeMillis()、Calendar.getInstance().getTimeInMillis()获取时间戳的方法
		FileUtils.copyFile(elementSnapshot(element), new File("屏幕截图", System.currentTimeMillis()+".png"));
		Thread.sleep(2000);
		driver.quit();
		
	}
 
	
	public static File elementSnapshot(WebElement element) throws Exception {
		//创建全屏截图
		WrapsDriver wrapsDriver = (WrapsDriver)element;
		File screen = ((TakesScreenshot)wrapsDriver.getWrappedDriver()).getScreenshotAs(OutputType.FILE);
		BufferedImage image = ImageIO.read(screen);
		//获取元素的高度、宽度
		int width = element.getSize().getWidth();
		int height = element.getSize().getHeight();
		
		//创建一个矩形使用上面的高度，和宽度
		Rectangle rect = new Rectangle(width, height);
		//元素坐标
		Point p = element.getLocation();
		BufferedImage img = image.getSubimage(p.getX(), p.getY(), rect.width, rect.height);
		ImageIO.write(img, "png", screen);
		return screen;
	}
	
	
}
