selenium截图操作

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selenium截图操作_第1张图片

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();
		
		/**
		 * 截屏操作
		 * 图片已当前时间命名
		 */
		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();
		
	}
	
	/**
	 * 截屏方法二、Robot实现截屏
	 * @throws Exception
	 */
	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();
		
	}

	/**
	 * 部分截图(元素截图)
	 * 有时候需要元素的截图,不需要整个截图
	 * @throws Exception 
	 */
	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;
	}
	
	
}
