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#

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);
}

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);
                }
    
            }

Java

我解决了这个问题。你可以扩展RemoteWebDriver，给它所有的接口，它的代理驱动程序实现:

WebDriver augmentedDriver = new Augmenter().augment(driver);
((TakesScreenshot)augmentedDriver).getScreenshotAs(...); // It works this way

是的，可以使用Selenium WebDriver对网页进行快照。

WebDriver API提供的getScreenshotAs()方法为我们做了这项工作。

语法:getScreenshotAs(OutputType<X> target)

返回类型:X

参数:target—查看OutputType提供的选项

适用性:不特定于任何DOM元素

例子:

    TakesScreenshot screenshot = (TakesScreenshot) driver;
    File file = screenshot.getScreenshotAs(OutputType.FILE);

有关详细信息，请参阅下面的工作代码片段。

    public class TakeScreenShotDemo {

        public static void main(String[] args) {
            WebDriver driver = new FirefoxDriver();
            driver.manage().window().maximize();
            driver.get(“http: //www.google.com”);

            TakesScreenshot screenshot = (TakesScreenshot) driver;

            File file = screenshot.getScreenshotAs(OutputType.FILE);

            // Creating a destination file
            File destination = new File(“newFilePath(e.g.: C: \\Folder\\ Desktop\\ snapshot.png)”);
            try {
                FileUtils.copyFile(file, destination);
            } catch (IOException e) {
                e.printStackTrace();
            }

        }
    }

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
