【问题描述】：
我在 .NET Core 2.0 项目中创建了 NUnit 测试。我想使用 VsTest - TestAssemblies 将它们作为VSTS 版本的一部分运行。当我在 VSTS 中为我的 DLL 运行此步骤时，我收到以下错误（或者更确切地说是警告），并且没有发现任何测试。当我在本地计算机上运行 VsTest.console.exe 时，相同的 DLL 可以工作。

为什么在我的本地机器上发现了 xmlDocument.dll，但在 VSTS 上却没有发现？
在我的本地文件夹中，我也没有 XmlDocument.dll。
【问题讨论】：
-
您是如何为 .net core 2.0 应用添加 nunit 测试的？您可以在一个驱动器中添加您的项目吗？并且请检查是否在.csproj中本地添加了一些引用。
-
我使用 nuget 添加了它：Nunit (3.9.0) 和 NUnit3TestAdapter (3.9.0)。 .csproj 中没有此 dll 的引用。此外，我设法让它与 vsts 中的 dotnet 测试任务一起工作，但不能与 vstest 一起工作。问题是，对于 dotnet 测试任务，我无法将 dll 定义为仅 csproj 的输入，这还不够好，因为我正在从其他目录复制构建的工件。你是否知道 vsts 中的 vstest 和 dotnet 测试任务有什么区别？
-
VS 测试任务还应该为 .net 核心应用程序构建 nunit 测试。并且 dotnet test 不需要指定 dll，因为它已经指定了项目。
-
我遇到了同样的问题。有解决办法吗？
