Java

这里似乎没有-在Java中截取一个特定元素的截图:

public void takeScreenshotElement(WebElement element) throws IOException {
    WrapsDriver wrapsDriver = (WrapsDriver) element;
    File screenshot = ((TakesScreenshot) wrapsDriver.getWrappedDriver()).getScreenshotAs(OutputType.FILE);
    Rectangle rectangle = new Rectangle(element.getSize().width, element.getSize().height);
    Point location = element.getLocation();
    BufferedImage bufferedImage = ImageIO.read(screenshot);
    BufferedImage destImage = bufferedImage.getSubimage(location.x, location.y, rectangle.width, rectangle.height);
    ImageIO.write(destImage, "png", screenshot);
    File file = new File("//path//to");
    FileUtils.copyFile(screenshot, file);
}

你可以在浏览器中截取网页可见部分的截图:

首先导入:

import java.io.File;
import com.google.common.io.Files;

Then

File src=((TakesScreenshot)driver).getScreenShotAs(OutputType.FILE);
Files.copy(src,new File("new path/pic.jpeg"));

另外，在Selenium4之后，你还可以截取webelement的截图:

WebElement element=driver.findElement(By.xpath("xpath 
 here"));
File src=element.getScreenShotAs(OutputType.FILE);
File.copy(src,new File("new path/pic.jpeg"));

C#

public void TakeScreenshot()
{
    try
    {            
        Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
        ss.SaveAsFile(@"D:\Screenshots\SeleniumTestingScreenshot.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
        throw;
    }
}

c#代码

IWebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((ITakesScreenshot)driver).GetScreenshotAs(OutputType.FILE);

// Now you can do whatever you need to do with it, for example copy somewhere
FileUtils.copyFile(scrFile, new File("c:\\tmp\\screenshot.png"));

硒化/ Java

以下是Selenide项目是如何做到这一点的，这比任何其他方式都要简单:

import static com.codeborne.selenide.Selenide.screenshot;    
screenshot("my_file_name");

JUnit:

@Rule
public ScreenShooter makeScreenshotOnFailure = 
     ScreenShooter.failedTests().succeededTests();

美国小妞TestNG:

import com.codeborne.selenide.testng.ScreenShooter;
@Listeners({ ScreenShooter.class})

File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
BufferedImage originalImage = ImageIO.read(scrFile);
//int type = originalImage.getType() == 0 ? BufferedImage.TYPE_INT_ARGB : originalImage.getType();
BufferedImage resizedImage = CommonUtilities.resizeImage(originalImage, IMG_HEIGHT, IMG_WIDTH);
ImageIO.write(resizedImage, "jpg", new File(path + "/"+ testCaseId + "/img/" + index + ".jpg"));
Image jpeg = Image.getInstance(path + "/" + testCaseId + "/img/"+ index + ".jpg");
