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);
                }
    
            }

Ruby

time = Time.now.strftime('%a_%e_%Y_%l_%m_%p_%M_%S')
file_path = File.expand_path(File.dirname(__FILE__) + 'screens_shot')+'/'+time +'.png'
#driver.save_screenshot(file_path)
page.driver.browser.save_screenshot file_path

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);
}

Java

对于较新版本的Java, FileUtils函数不起作用。在这里，下面的功能可以完美地复制屏幕截图。

import java.io.File;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.io.FileHandler;

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
File destfile = new File(destination folder /filename.extension);
FileHandler.copy(scrfile, destfile);

Python

def test_url(self):
    self.driver.get("https://www.google.com/")
    self.driver.save_screenshot("test.jpg")

它将在脚本保存的同一目录下保存一个截图。

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"));
