是否可以使用Selenium WebDriver进行截图?

(注:不含硒遥控器)

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));
    }
  }

我使用下面的c#代码来获取整个页面或仅一个浏览器截图

    public void screenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            ITakesScreenshot screen = driverScript.driver as ITakesScreenshot;
            Screenshot screenshot = screen.GetScreenshot();
            screenshot.SaveAsFile(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Fail see Exception", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside screenShot");
        }
    }

    public void fullPageScreenShot(string tcName)
    {
        try
        {
            string dateTime = string.Format("{0:yyyy-MM-dd_hh-mm-ss-tt}", DateTime.Now);
            string screenShotName = @"D:\Selenium\Project\VAM\VAM\bin" + "\\" + tcName + dateTime + ".png";
            Rectangle bounds = Screen.GetBounds(Point.Empty);
            using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
            {
                using (Graphics g = Graphics.FromImage(bitmap))
                {
                    g.CopyFromScreen(Point.Empty, Point.Empty, bounds.Size);
                }
                bitmap.Save(screenShotName, System.Drawing.Imaging.ImageFormat.Png);
            }
            if (driverScript.last == 1)
                this.writeResult("Sheet1", "Pass", "Status", driverScript.resultRowID);
        }
        catch (Exception ex)
        {
            driverScript.writeLog.writeLogToFile(ex.ToString(), "inside fullPageScreenShot");
        }
    }

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

PowerShell

Set-Location PATH:\to\selenium

Add-Type -Path "Selenium.WebDriverBackedSelenium.dll"
Add-Type -Path "ThoughtWorks.Selenium.Core.dll"
Add-Type -Path "WebDriver.dll"
Add-Type -Path "WebDriver.Support.dll"

$driver = New-Object OpenQA.Selenium.PhantomJS.PhantomJSDriver

$driver.Navigate().GoToUrl("https://www.google.co.uk/")

# Take a screenshot and save it to filename
$filename = Join-Path (Get-Location).Path "01_GoogleLandingPage.png"
$screenshot = $driver.GetScreenshot()
$screenshot.SaveAsFile($filename, [System.Drawing.Imaging.ImageFormat]::Png)

其他司机……

$driver = New-Object OpenQA.Selenium.Chrome.ChromeDriver
$driver = New-Object OpenQA.Selenium.Firefox.FirefoxDriver
$driver = New-Object OpenQA.Selenium.IE.InternetExplorerDriver
$driver = New-Object OpenQA.Selenium.Opera.OperaDriver

C#

你可以使用下面的代码片段/函数用Selenium截图:

    public void TakeScreenshot(IWebDriver driver, string path = @"output")
    {
        var cantakescreenshot = (driver as ITakesScreenshot) != null;
        if (!cantakescreenshot)
            return;
        var filename = string.Empty + DateTime.Now.Hour + DateTime.Now.Minute + DateTime.Now.Second + DateTime.Now.Millisecond;
        filename = path + @"\" + filename + ".png";
        var ss = ((ITakesScreenshot)driver).GetScreenshot();
        var screenshot = ss.AsBase64EncodedString;
        byte[] screenshotAsByteArray = ss.AsByteArray;
        if (!Directory.Exists(path))
            Directory.CreateDirectory(path);
        ss.SaveAsFile(filename, ImageFormat.Png);
    }

Java

使用RemoteWebDriver,在增加了节点的截图功能后,我将像这样存储截图:

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();
    }
}

你可以在任何需要的地方使用这种方法。然后,我假设您可以在surefire-reports/html/custom.css中定制maven-surefire-report-plugin的样式表,以便您的报告包含到每个测试的正确截图的链接。
