.net core VSTS生成：测试运行，但测试失败，报告为失败，并带有“0”；Vstest失败，出现错误。检查日志中的故障。可能会有失败的测试。”；

我需要一些VSTS托管构建的帮助

在托管的VSTS生成上，运行测试任务运行测试，但随后被标记为失败，尽管测试实际正在运行

相关线路为：

System.IO.FileNotFoundException:找不到的测试 D:\a\1\s\src\XXX.YYY.IntegrationTests\obj\Release\netcoreapp2.1\XXX.yy.IntegrationTests.dll。 确保测试项目具有包的nuget引用 “Microsoft.NET.Test.Sdk”和框架版本设置 适当的使用/diag选项重新运行以进一步诊断。（……更多 此处，请参见下文）[警告]Vstest因错误而失败。检查日志 因为失败。可能有失败的测试。[错误]错误：C:\Program 文件（x86）\Microsoft Visual Studio Studio\2017\Enterprise\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe 失败，返回代码：1

所有测试项目都引用了

Microsoft.NET.test.Sdk

15.8.0。 MSTest.TestAdapter和MSTest.TestFramework都是v1.3.2

更新 如果我在本地运行

“C:\ProgramFiles（x86）\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\vstest.console.exe”“path/to/dlls/X.Tests.dll”

我明白了

警告：（…）中没有可用的测试。确保已安装测试
发现者和执行者、平台和框架版本设置
请选择合适的，然后重试。

如果我运行

“C:\Program Files（x86）\Microsoft Visual Studio\2017\BuildTools\Common7\IDE\Extensions\TestPlatform\vstest.console.exe”

，则不会出现警告，测试将运行

提前感谢您的帮助。

根据错误消息和您在本地计算机上运行的命令，您的测试DLL中应该存在一些问题。请创建一个简单的单元测试项目，并使用VsTest任务运行此单元测试dll，以检查它是否也存在相同的问题。@WeiweiCai MSFT“根据错误消息和您在本地计算机上运行的命令，您的测试dll中应该存在一些问题”是什么意思？这说明了什么？如果我用一个版本的testrunner运行它，它会工作，如果用另一个版本运行它，它不会工作。这不是真正的问题。问题是测试运行了，但是构建被标记为失败，这是因为幻象导致的错误。我再强调也不过分，测试实际上是在运行的——它们怎么会丢失并同时运行呢？
