File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
BufferedImage originalImage = ImageIO.read(scrFile);
//int type = originalImage.getType() == 0 ? BufferedImage.TYPE_INT_ARGB : originalImage.getType();
BufferedImage resizedImage = CommonUtilities.resizeImage(originalImage, IMG_HEIGHT, IMG_WIDTH);
ImageIO.write(resizedImage, "jpg", new File(path + "/"+ testCaseId + "/img/" + index + ".jpg"));
Image jpeg = Image.getInstance(path + "/" + testCaseId + "/img/"+ index + ".jpg");

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"));

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)')

是的，可以通过Selenium WebDriver来截屏。我目前使用Chrome驱动来抓取网站图片。请参考以下方法captureScreenshot()。

您还可以添加对web驱动程序的限制，例如

使用无头版的网页浏览器 当页面加载时禁用通知 启动全屏等。

如果一个网站配备了警报框，你的网页驱动程序将无法捕捉屏幕截图，因为异常将被抛出。在这种情况下，你需要关闭警告框，然后获取截图。下面的代码片段关闭警报框。

    public void captureScreenshot() throws InterruptedException, IOException {

        System.out.println("Creating Chrome Driver");

        // Set Chrome Driver
        System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");

        // Add arguments to Chrome Options
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("--headless");
        chromeOptions.addArguments("start-maximized");
        chromeOptions.addArguments("--disable-gpu");
        chromeOptions.addArguments("--start-fullscreen");
        chromeOptions.addArguments("--disable-extensions");
        chromeOptions.addArguments("--disable-popup-blocking");
        chromeOptions.addArguments("--disable-notifications");
        chromeOptions.addArguments("--window-size=1920,1080");
        chromeOptions.addArguments("--no-sandbox");
        chromeOptions.addArguments("--dns-prefetch-disable");
        chromeOptions.addArguments("enable-automation");
        chromeOptions.addArguments("disable-features=NetworkService");

        WebDriver driver = new ChromeDriver(chromeOptions);
        driver.get("https://www.google.com");
        System.out.println("Wait a bit for the page to render");
        TimeUnit.SECONDS.sleep(5);
        System.out.println("Taking Screenshot");
        File outputFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
        String imageDetails = "D:\\Images";
        File screenShot = new File(imageDetails).getAbsoluteFile();
        FileUtils.copyFile(outputFile, screenShot);
        System.out.println("Screenshot saved: {}" + imageDetails);
    }
}

为了接受警报框和获取截图:

String alertText = alert.getText();
System.out.println("ERROR: (ALERT BOX DETECTED) - ALERT MSG : " + alertText);
alert.accept();
File outputFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
String imageDetails = "D://Images"
File screenShot = new File(imageDetails).getAbsoluteFile();
FileUtils.copyFile(outputFile, screenShot);
System.out.println("Screenshot saved: {}" + imageDetails);
driver.close();

硒化/ Java

以下是Selenide项目是如何做到这一点的，这比任何其他方式都要简单:

import static com.codeborne.selenide.Selenide.screenshot;    
screenshot("my_file_name");

JUnit:

@Rule
public ScreenShooter makeScreenshotOnFailure = 
     ScreenShooter.failedTests().succeededTests();

美国小妞TestNG:

import com.codeborne.selenide.testng.ScreenShooter;
@Listeners({ ScreenShooter.class})

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);
}
