使用c#和MSTestframework， 这里我创建了一个静态方法。采取了一个路径，我可以将图像存储为jpeg格式。为了更清楚，我用当前正在执行的测试用例和失败的日期和时间来命名这些屏幕截图。

          /// <summary>
            /// This method is used to screen shot where test method failed 
            /// </summary>
            /// <param name="testCase">TestCaseName</param>
            public static void Capture(string testCase)
            {
                try
                {
                    StringBuilder path = new StringBuilder("C:/Logs/Screenshot/");
                    Constant.screenshot = ((ITakesScreenshot)Constant.browser).GetScreenshot();
                    string fileName = path.Append(string.Format(testCase + "-at-{0:yyyy-MM dd_hh-mm-ss}.jpeg", DateTime.Now)).ToString();
                    Constant.screenshot.SaveAsFile(fileName, ScreenshotImageFormat.Jpeg);
                }
                catch (Exception e)
                {
                    File.AppendAllText("C:/Logs/FailedTestCasesLogs.txt", "\nCOULD NOT CAPTURE THE SCREENSHOT!\n");
                    Log(e);
                }
    
            }

你可以使用Webdriverclass对象创建一个webdriver支持的selenium对象，然后你可以截屏。

import java.io.File;
import java.io.IOException;

import org.apache.maven.surefire.shade.org.apache.maven.shared.utils.io.FileUtils;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
/**

public class ScreenShotMaker {

    // take screen shot on the test failures
    public void takeScreenShot(WebDriver driver, String fileName) {
        File screenShot = ((TakesScreenshot) driver)
                .getScreenshotAs(OutputType.FILE);
        try {
            FileUtils.copyFile(screenShot, new File("src/main/webapp/screen-captures/" + fileName + ".png"));

        } catch (IOException ioe) {
            throw new RuntimeException(ioe.getMessage(), ioe);
        }
    }

}

C#

public static void TakeScreenshot(IWebDriver driver, String filename)
{
    // Take a screenshot and save it to filename
    Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();
    screenshot.SaveAsFile(filename, ImageFormat.Png);
}

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。

Java

在附加TestName和Timestamp的情况下为Selenium中的失败捕获屏幕截图的方法。

public class Screenshot{
    final static String ESCAPE_PROPERTY = "org.uncommons.reportng.escape-output";
    public static String imgname = null;

    /*
     * Method to Capture Screenshot for the failures in Selenium with TestName and Timestamp appended.
     */
    public static void getSnapShot(WebDriver wb, String testcaseName) throws Exception {
      try {
      String imgpath = System.getProperty("user.dir").concat("\\Screenshot\\"+testcaseName);
      File f = new File(imgpath);
      if(!f.exists())   {
          f.mkdir();
        }
        Date d = new Date();
        SimpleDateFormat sd = new SimpleDateFormat("dd_MM_yy_HH_mm_ss_a");
        String timestamp = sd.format(d);
        imgname = imgpath + "\\" + timestamp + ".png";

        // Snapshot code
        TakesScreenshot snpobj = ((TakesScreenshot)wb);
        File srcfile = snpobj.getScreenshotAs(OutputType.FILE);
        File destFile = new File(imgname);
        FileUtils.copyFile(srcfile, destFile);

      }
      catch(Exception e) {
          e.getMessage();
      }
   }
