C#

public Bitmap TakeScreenshot(By by) {
    // 1. Make screenshot of all screen
    var screenshotDriver = _selenium as ITakesScreenshot;
    Screenshot screenshot = screenshotDriver.GetScreenshot();
    var bmpScreen = new Bitmap(new MemoryStream(screenshot.AsByteArray));

    // 2. Get screenshot of specific element
    IWebElement element = FindElement(by);
    var cropArea = new Rectangle(element.Location, element.Size);
    return bmpScreen.Clone(cropArea, bmpScreen.PixelFormat);
}

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"));

Java

public String captureScreen() {
    String path;
    try {
        WebDriver augmentedDriver = new Augmenter().augment(driver);
        File source = ((TakesScreenshot)augmentedDriver).getScreenshotAs(OutputType.FILE);
        path = "./target/screenshots/" + source.getName();
        FileUtils.copyFile(source, new File(path)); 
    }
    catch(IOException e) {
        path = "Failed to capture screenshot: " + e.getMessage();
    }
    return path;
}

Java (Robot Framework)

我使用这种方法进行截图。

void takeScreenShotMethod(){
    try{
        Thread.sleep(10000)
        BufferedImage image = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
        ImageIO.write(image, "jpg", new File("./target/surefire-reports/screenshot.jpg"));
    }
    catch(Exception e){
        e.printStackTrace();
    }
}

你可以在任何需要的地方使用这种方法。

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");

C# （Ranorex API）

public static void ClickButton()
{
    try
    {
        // code
    }
    catch (Exception e)
    {
        TestReport.Setup(ReportLevel.Debug, "myReport.rxlog", true);
        Report.Screenshot();
        throw (e);
    }
}
