是否可以使用Selenium WebDriver进行截图?

我无法得到可接受的答案,但根据当前的WebDriver文档,以下内容对我来说在OS X v10.9 (Mavericks)上的Java 7工作得很好:

import java.io.File;
import java.net.URL;

import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.remote.Augmenter;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;

public class Testing {

   public void myTest() throws Exception {
       WebDriver driver = new RemoteWebDriver(
               new URL("http://localhost:4444/wd/hub"),
               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);
   }
}

我想我应该给出完整的解决方案,因为有两种不同的方法获得截图。一个来自本地浏览器,另一个来自远程浏览器。我甚至将图像嵌入到HTML报告中:

@After()
public void selenium_after_step(Scenario scenario) throws IOException, JSONException {

    if (scenario.isFailed()){

        scenario.write("Current URL = " + driver.getCurrentUrl() + "\n");

        try{
            driver.manage().window().maximize();  // Maximize window to get full screen for chrome
        }
        catch (org.openqa.selenium.WebDriverException e){
            System.out.println(e.getMessage());
        }

        try {
            if(isAlertPresent()){
                Alert alert = getAlertIfPresent();
                alert.accept();
            }
            byte[] screenshot;
            if(false /*Remote Driver flow*/) { // Get a screenshot from the remote driver
                Augmenter augmenter = new Augmenter();
                TakesScreenshot ts = (TakesScreenshot) augmenter.augment(driver);
                screenshot = ts.getScreenshotAs(OutputType.BYTES);
            } 
            else { // Get a screenshot from the local driver
                // Local webdriver user flow
                screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES);
            }
            scenario.embed(screenshot, "image/png"); // Embed the image in reports
        } 
        catch (WebDriverException wde) {
            System.err.println(wde.getMessage());
        } 
        catch (ClassCastException cce) {
            cce.printStackTrace();
        }
    }

    //seleniumCleanup();
}

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

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");
        }
    }

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));
    }
  }

C#

public void TakeScreenshot()
{
    try
    {            
        Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
        ss.SaveAsFile(@"D:\Screenshots\SeleniumTestingScreenshot.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
        throw;
    }
}
