【问题描述】：
我无法从 VS 内部运行测试。我只用模板中的一个 NUnit 测试项目和一个使用 Assert.IsTrue(true) 的测试创建了最简单的解决方案。
以下是我添加到项目中的 NuGet 包及其版本，以防万一：
- Microsoft.NET.Test.Sdk 16.8.0
- NUnit 3.12.0
- NUnit3TestAdapter 3.17.0
这是我使用 dotnet test [projName] 从命令行运行测试时得到的输出：
Determining projects to restore...
Restored /Users/OpenMinder/DevTraining/Test/Test.csproj (in 331 ms).
Test -> /Users/OpenMinder/DevTraining/Test/bin/Debug/netcoreapp3.1/Test.dll
Test run for /Users/OpenMinder/DevTraining/Test/bin/Debug/netcoreapp3.1/Test.dll (.NETCoreApp,Version=v3.1)
Microsoft (R) Test Execution Command Line Tool Version 16.8.0
Copyright (c) Microsoft Corporation. All rights reserved.
Starting test execution, please wait...
A total of 1 test files matched the specified pattern.
Passed! - Failed: 0, Passed: 1, Skipped: 0, Total: 1, Duration: 29 ms - /Users/OpenMinder/DevTraining/Test/bin/Debug/netcoreapp3.1/Test.dll (netcoreapp3.1)
但每当我尝试从 VS for mac 运行它们时，我都会得到以下行为：
-
测试名称不显示在面板中
-
测试运行未完成
-
我在输出中收到以下错误：

有人知道我还能尝试什么吗？
如果您需要更多信息，请告诉我。
【问题讨论】：
-
在终端，
dotnet test告诉你什么？ -
嗨@LexLi 我已将 dotnet 测试的结果添加到描述中。对我来说这看起来很正常。我知道我总是可以以这种方式运行测试，但我需要一个 VS IDE 来用于我正在启动的项目，而且我很确定在某些时候我需要调试测试。
-
两者比较表明
dotnet test只检测/Users/OpenMinder/DevTraining/Test为测试项目，而VS for Mac检测/Users/OpenMinder/Dev training/eco-bonus/Api/Api.UnitTests为测试项目。您可能会进一步挖掘，看看可能出了什么问题。 -
@LexLi 好地方，但那是我的错误。输出来自我的真实项目，但 dotnet 测试结果来自更简单的版本。我现在更新了输出日志以匹配更简单的解决方案。看起来可疑的是，在输出日志中它正在寻找 microsoft.testplatform.testhost 包的 netcoreapp2.1 版本，并且该项目位于 .NET Core 3.1 中（我没有此包的 netcoreapp3.1 文件夹即使是最新的稳定版本 16.8.0）。
