捕捉视频
有时候我们未必能够分析故障只需用日志文件或截图的帮助。有时捕获完整的执行视频帮助。让我们了解如何捕捉视频。

我们将利用Monte媒体库的执行相同。

配置

第1步：导航到URL下载屏幕记录JAR，如下图所示。
http://www.randelshofer.ch/monte/index.html

第2步：下载后，添加JAR文件添加到当前项目的库。

第3步：我们会利用Java的AWT包来初始化显卡配置。

GraphicsConfiguration gc = GraphicsEnvironment
  .getLocalGraphicsEnvironment()
  .getDefaultScreenDevice()
  .getDefaultConfiguration();
  
第4步：它采用下列参数创建ScreenRecorder的一个实例。

 
示例

我们将捕获简单的测试执行视频 - 百分比计算。

        File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

        FileUtils.copyFile(screenshot, new File("D:screenshotsscreenshots1.jpg"));

        // 停止捕获视频
        screenRecorder.stop();
    }
}

输出

录制的视频保存在“C:users<<UserName>>Videos”文件夹，如下图所示。
