来自 TFS2015 的 xunit - 在哪里放置 ParallelizeAssemblies
xunit from TFS2015 - where to put ParallelizeAssemblies
我正在尝试加快我们的单元测试。通过在 app.config 文件中将 xunit.parallelizeAssembly 设置为 true，当 运行 来自 Visual Studio 时，我可以并行地从不同的程序集对 运行 进行多个测试。但是当 运行ning 在构建服务器上时，执行时间没有任何区别，我可以看到只使用了一个内核。
在 this 页面上关于 MSBuild Runner 的段落中，建议设置 ParallelizeAssemblies 可以解决此问题。我目前正在 运行 使用 "Visual Studio Test" 构建步骤进行测试（参见图片了解配置）。我把这个设置放在哪里？
我不能分享所有日志，但我相信第一部分和最后一部分可能包含很好的线索。
