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(); /** * 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; } }
