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();
            }

        }
    }

Python

webdriver.get_screenshot_as_file(filepath)

上述方法将截取屏幕截图，并将其作为文件存储在作为参数提供的位置中。

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);
                }
    
            }

Set-Location PATH:\to\selenium

Add-Type -Path "Selenium.WebDriverBackedSelenium.dll"

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})

PHP

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));
    }
  }
