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

是的，这是可能的。下面以Java为例:

WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com/");
File scrFile = ((TakesScreenshot)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"));

我使用下面的c#代码来获取整个页面或仅一个浏览器截图

    public void screenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            ITakesScreenshot screen = driverScript.driver as ITakesScreenshot;
            Screenshot screenshot = screen.GetScreenshot();
            screenshot.SaveAsFile(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Fail see Exception", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside screenShot");
        }
    }

    public void fullPageScreenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            Rectangle bounds = Screen.GetBounds(Point.Empty);
            using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
            {
                using (Graphics g = Graphics.FromImage(bitmap))
                {
                    g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
                }
                bitmap.Save(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            }
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Pass", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside fullPageScreenShot");
        }
    }

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);
                }
    
            }

Python

您可以使用Python web驱动程序从windows中捕获图像。使用下面的代码哪个页面需要捕获屏幕截图。

driver.save_screenshot('c:\foldername\filename.extension(png, jpeg)')

Java

public void captureScreenShot(String obj) throws IOException {
    File screenshotFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
    FileUtils.copyFile(screenshotFile, new File("Screenshots\\" + obj + "" + GetTimeStampValue() + ".png"));
}

public String GetTimeStampValue()throws IOException{
    Calendar cal = Calendar.getInstance();
    Date time = cal.getTime();
    String timestamp = time.toString();
    System.out.println(timestamp);
    String systime = timestamp.replace(":", "-");
    System.out.println(systime);
    return systime;
}

使用这两种方法，您还可以拍摄带有日期和时间的屏幕截图。
