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。
