vstest 与 TFS 生成：System.Runtime.Remoting.RemotingException："对象'/XXX.rem'已断开连接或服务器上不存在

Question

我有一个带有单元测试的x64 .NET 4.5.2 C#解决方案。

单元测试在我的开发计算机上成功运行，但在 TFS 生成上运行时，使用以下命令：

[command]"D:Program Files (x86)Microsoft Visual Studio 14.0Common7IDECommonExtensionsMicrosoftTestWindowvstest.console.exe" m:WorkspaceMyAppTestsMyApp.Testsbinx64ReleaseMyApp.Tests.dll /logger:trx "/TestAdapterPath:"m:Workspace"" /Platform:x64

我收到以下日志：

Microsoft (R( 测试执行命令行工具版本 14.0.25420.1 版权所有 (c( Microsoft公司。 保留所有权利。开始 测试执行，请稍候...

5分钟挂起，然后

错误：调用执行程序时发生异常 "executor://mstestadapter/v2"：对象 '/5243803c_c5e9_4f2c_bd7d_05acf3030dfa/veajeovlsl8zvqsxjaq47f1d_25.rem' 服务器已断开连接或不存在。

这总是在构建服务器上重现，我设法使用 debbugger 重现了一次并得到了以下堆栈跟踪：

System.Runtime.Remoting.RemotingException: 'Object '/5594bcf8_9093_482c_aa7b_bb6b6f25dd27/gudsmiyjksi5no4zhgahfzqu_9.rem' has been disconnected or does not exist at the server.'

我尝试同时使用Visual Studio 2015和2017，得到了相同的结果。

我的解决方案是使用MSTest.TestAdapter和MSTest.TestFramework版本 1.1.11 的包

根据此线程：标记为通过的长时间运行的单元测试失败 TFS 生成 - 对象"xxx.rem"已断开连接或服务器上不存在。

我尝试升级MSTest包版本，但永远无法使它们以更高版本在本地运行。

此外，我之前也使用 1.1.11 包成功地对其他项目运行单元测试。

Answer 1

是的，这是旧版本上MSTest的问题。

因此，解决方案是在生成代理计算机上将 MSTest 升级到 1.1.13 或更高版本。
