| 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 - http://www.randelshofer.ch/monte/index.htmll和下载屏幕记录JAR，如下图所示。
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"));
//Print a Log In message to the screen
System.out.println(" The Result is
" + result);
//Close the Browser.
driver.close();
// Stop the ScreenRecorder
screenRecorder.stop();
}

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