是否可以使用Selenium WebDriver进行截图?

(注:不含硒遥控器)


当前回答

PHP (PHPUnit)

它使用PHPUnit_Selenium扩展版本1.2.7:

class MyTestClass extends PHPUnit_Extensions_Selenium2TestCase {
    ...
    public function screenshot($filepath) {
        $filedata = $this->currentScreenshot();
        file_put_contents($filepath, $filedata);
    }

    public function testSomething() {
        $this->screenshot('/path/to/screenshot.png');
    }
    ...
}

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();
}

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);
                }
    
            }

C# (Ranorex API)

public static void ClickButton()
{
    try
    {
        // code
    }
    catch (Exception e)
    {
        TestReport.Setup(ReportLevel.Debug, "myReport.rxlog", true);
        Report.Screenshot();
        throw (e);
    }
}

Java

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);
   }
}

Java

在附加TestName和Timestamp的情况下为Selenium中的失败捕获屏幕截图的方法。

public class Screenshot{
    final static String ESCAPE_PROPERTY = "org.uncommons.reportng.escape-output";
    public static String imgname = null;

    /*
     * Method to Capture Screenshot for the failures in Selenium with TestName and Timestamp appended.
     */
    public static void getSnapShot(WebDriver wb, String testcaseName) throws Exception {
      try {
      String imgpath = System.getProperty("user.dir").concat("\\Screenshot\\"+testcaseName);
      File f = new File(imgpath);
      if(!f.exists())   {
          f.mkdir();
        }
        Date d = new Date();
        SimpleDateFormat sd = new SimpleDateFormat("dd_MM_yy_HH_mm_ss_a");
        String timestamp = sd.format(d);
        imgname = imgpath + "\\" + timestamp + ".png";

        // Snapshot code
        TakesScreenshot snpobj = ((TakesScreenshot)wb);
        File srcfile = snpobj.getScreenshotAs(OutputType.FILE);
        File destFile = new File(imgname);
        FileUtils.copyFile(srcfile, destFile);

      }
      catch(Exception e) {
          e.getMessage();
      }
   }
