c# - 如何在 .NetCore 中使用 Selenium C# 记录测试执行

Question

我正在尝试使用Selenium, C#, MSTestin记录测试执行.NetCore

尝试使用 Microsoft.Express.Encoder nuget pkg，它在创建 ScreenCaptureJob 实例时引发错误

 "System.BadImageFormatException: Could not load file or assembly 'Microsoft.Expression.Encoder, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. An attempt was made to load a program with an incorrect format." To resolve this, tried running test using x86, x64 and Any CPU, but none of them works.

Also tried using Nunit.Video.Recorder, with Nunit Framework, when did this, test are not discovered, tried changing to x86, x64 and Any CPU

如果您在安装了 Visual Studio 的 Windows 环境中，则可以在 . 运行设置文件。

<DataCollector uri="datacollector://microsoft/VideoRecorder/1.0" assemblyQualifiedName="Microsoft.VisualStudio.TestTools.DataCollection.VideoRecorder.VideoRecorderDataCollector, Microsoft.VisualStudio.TestTools.DataCollection.VideoRecorder, Version=15.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" friendlyName="Screen and Voice Recorder">
<!--Video data collector was introduced in Visual Studio 2017 version 15.5 -->
</DataCollector>

如果您使用数据收集器，我建议从测试运行器输出 TRX 文件日志，以便您可以映射哪些视频与哪些测试一起使用。

其他选项包括使用 Selenium Grid 或使用 ffmpeg.net 通过类似 ffmpeg 的方式实现您自己的记录器调用，请参阅此问题。

这是启动和停止ffmpeg的直接方法

    var si = new ProcessStartInfo
    {
        Arguments = "-y -f gdigrab -framerate 10 -video_size 1920x1080 -i desktop output.mp4",
        FileName = _fixture.FFmpegPath,
        RedirectStandardInput = true,            
    };

    var ffmpegProcess = Process.Start(si);
    await Task.Delay(15000);
    ffmpegProcess.StandardInput.Write("q");
    ffmpegProcess.WaitForExit();
