如何在Java中使用selenium webdriver截取失败的测试用例的屏幕截图？

Question

任何人都可以在使用java运行selenium webdriver自动化脚本时帮助拍摄屏幕截图并保存在Mac上的特定文件夹？

注：我在代码中使用静态的，所以我不能下面的代码

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); 
FileUtils.copyFile(scrFile, new File("D:\\screenshot.jpg")); 

在此先感谢！使用

Answer 1

您不需要为截图文件（如“screenshot.jpg”）创建静态名称，只需在每次拍摄屏幕截图时都进行更改。你可以用许多不同的方式做什么。

一个你必须在这种情况下就可以了，创建日期和时间的字符串，将是唯一的，这样的选项：

var myUniqueScreenshot = "D:\\"+DateTime.Now.ToString("F").Replace(":", "-")+".jpg"; 

File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); 
FileUtils.copyFile(scrFile, new File(myUniqueScreenshot)); 

的第一行代码是C＃希望你可以把它翻译成Java，如果它不一样。

您可以创建一些包装操作来解决您的问题。在这里，我为你分享一个java例子。希望能帮助到你。

ScreenshotUtil.java

public class ScreenshotUtil { 
    public static void capture(WebDriver driver) { 
     File src = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); 
     StringBuffer failedPicPath = new StringBuffer(); 
     failedPicPath.append("D:\\"); 
     String fn = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()).toString(); //Or the name you want. I suggest don't use static name. 
     failedPicPath.append(fn）; 
     failedPicPath.append(".jpg"); 
    } 
} 

Click.java

public void click(WebDriver driver, String xpath) { //Assume you are using Xpath 
    try { 
      WebElement e = FindElementUtil.find(driver, xpath); //Here you can design a class named FindElementUtil to search any elements and construct your own Exception. Then catch it here and out put Screenshots. 

      e.click(): 
    } catch(ANYEXCETPION e) { 
     ScreenshotUtil.capture(driver); //OR you want to capture pic in all situations, capture it in 'finally' block. 
    } 
}

新建文件夹

File file = new File("Screenshots" + fileSeperator + "Results"); 
      if (!file.exists()) { 
       file.mkdir(); 
      } 


//Now take the screens shot with name of your test method and copy to folder 
File screenshotFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); 
File targetFile = new File("Screenshots" + fileSeperator + "Results" + fileSeperator + testName, screenShotName); 
FileUtils.copyFile(screenshotFile, targetFile); 

Answer 4

如果你正在使用JUnit 4，您可以创建一个扩展TestWatcher类类。

public class ScreenShotRule extends TestWatcher { 

    private WebDriver webDriver; 

    public ScreenShotRule(WebDriver webDriver) { 
     this.webDriver = webDriver; 
    } 

    @Override 
    protected void failed(Throwable e, Description description) { 
     String methodName = description.getMethodName(); 
     String fileName = description.getTestClass().getSimpleName() + "-" + methodName + ".png"; 

     try { 
      File destiny = new File(fileName); 
      FileUtils.copyFile(((TakesScreenshot) webDriver).getScreenshotAs(OutputType.FILE), destiny); 
     } catch (IOException ioe) { 
      throw new RuntimeException(ioe); 
     } 
    } 

    @Override 
    protected void finished(Description description) { 
     webDriver.quit(); 
    } 
} 

在测试中，添加此类的公共字段，当测试失败时，规则将采用截图。

@Rule 
public ScreenShotRule screenshotRule;
