是的，这是可能的。以下示例是用 Java 编写的：

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"));

每个 WebDriver 都有一个方法。所以对于Firefox来说，它可以这样使用：.save_screenshot(filename)

from selenium import webdriver

browser = webdriver.Firefox()
browser.get('http://www.google.com/')
browser.save_screenshot('screenie.png')

令人困惑的是，还存在一种执行相同操作的方法。.get_screenshot_as_file(filename)

还有以下方法：（用于嵌入 HTML）和（用于检索二进制数据）。.get_screenshot_as_base64().get_screenshot_as_png()

请注意，WebElements 有一个类似的工作方法，但只捕获选定的元素。.screenshot()

红宝石

require 'rubygems'
require 'selenium-webdriver'

driver = Selenium::WebDriver.for :ie
driver.get "https://www.google.com"
driver.save_screenshot("./screen.png")

更多文件类型和选项可用，您可以在文件 takes_screenshot.rb 中看到它们。

我解决了这个问题。您可以增强 ，为其提供其代理驱动程序实现的所有接口：RemoteWebDriver

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

Java（机器人框架)

我用这种方法截屏。

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();
    }
}

您可以在需要时使用此方法。

使用 RemoteWebDriver，在使用屏幕截图功能增强 Node 后，我会像这样存储屏幕截图：

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

您可以在需要时使用此方法。然后，我假设您可以在 surefire-reports/html/custom.css 中自定义 maven-surefire-report-plugin 的样式表，以便您的报告包含指向每个测试的正确屏幕截图的链接？

PHP的

public function takescreenshot($event)
  {
    $errorFolder = dirname(dirname(__FILE__)) . DIRECTORY_SEPARATOR . "ErrorScreenshot";

    if(!file_exists($errorFolder)){
      mkdir($errorFolder);
    }

    if (4 === $event->getResult()) {
      $driver = $this->getSession()->getDriver();
      $screenshot = $driver->getWebDriverSession()->screenshot();
      file_put_contents($errorFolder . DIRECTORY_SEPARATOR . 'Error_' .  time() . '.png', base64_decode($screenshot));

我无法得到公认的答案，但根据当前的 WebDriver 文档，以下内容在 OS X v10.9 （Mavericks） 上使用 Java 7 对我来说效果很好：

               DesiredCapabilities.firefox());

       driver.get("http://www.google.com");

       // RemoteWebDriver does not implement the TakesScreenshot class
       // if the driver does have the Capabilities to take a screenshot
       // then Augmenter will add the TakesScreenshot methods to the instance
       WebDriver augmentedDriver = new Augmenter().augment(driver);
       File screenshot = ((TakesScreenshot)augmentedDriver).
               getScreenshotAs(OutputType.FILE);
   }
}

String yourfilepath = "E:\\username\\Selenium_Workspace\\foldername";

// Take a snapshort

FileUtils.copyFile(snapshort_file, new File(yourfilepath));

       driver.get("http://google.com")
       screenPnG = driver.get_screenshot_as_png()
  
       # Crop it back to the window size (it may be taller)
       box = (0, 0, 1366, 728)
       im = Image.open(BytesIO(screenPnG))
       region = im.crop(box)
       region.save('./Screenshots/get_screenshot_as_png_method.png', 'PNG', optimize=True, quality=95)
       driver.quit()
  

• 截图：

  

更新时间：2022

为了在 Selenium 中截取屏幕截图，我们使用一个名为 的接口，它使 Selenium WebDriver 能够捕获屏幕截图并以不同的方式存储它。它有一个捕获屏幕截图并将其存储在指定位置的方法。TakesScreenshotgetScreenshotAs()

//Convert webdriver to TakeScreenshot
File screenshotFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

在上面的代码中，它将 WebDriver 对象（驱动程序）转换为 TakeScreenshot。并调用方法通过提供参数来创建图像文件getScreenshotAs()*OutputType.FILE.

我们可以使用 File 对象将图像复制到我们想要的位置，如下所示，使用 .FileUtils Class

FileUtils.copyFile(screenshotFile , new File("C:\\temp\\screenshot.png));

捕获整个页面

Selenium WebDriver 不提供捕获整个页面屏幕截图的固有功能。要捕获整页屏幕截图，我们必须使用名为 Ashot 的第三方库。它提供了对特定 WebElement 进行屏幕截图以及整页屏幕截图的功能。

捕获屏幕大小图像

Screenshot screenshot = new Ashot().takeScreenshot(driver);

截取整页截图

Screenshot s=new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
ImageIO.write(s.getImage(),"PNG",new File("<< file path>>"));

在上面的代码中，1000 是以毫秒为单位的滚动时间。换句话说，这意味着程序将每 1000 毫秒滚动一次以截取屏幕截图。

捕获 elememnt

有两种方法可以在 Selenium 中捕获 Web 元素的屏幕截图。

• 获取全屏图像，然后根据 Web 元素的尺寸裁剪图像。
• 在 Web 元素上使用方法。（这仅在 selenium 版本 4.X 中可用）getScreenshotAs()
