MSTest v2 不能與 net5.0-windows 一起運行

Question

我正在嘗試為我們的 WinUI 3 開發的單元測試創建一個 MSTest 項目。 以 .NET 5.0 為目標時，我能夠通過測試資源管理器運行測試。

Project Reunion 需要 net5.0-windows10.0.19041 作為目標框架。 當我嘗試運行針對 net5.0-windows10.0.19041 的測試時，項目構建但測試不運行。 下面測試日志的 output 說 WinUI3-UnitTests.dll 文件未找到，但 WinUI3-UnitTests.dll 確實存在於指定位置。

[2021-10-05 9:38:57.350 AM] [MSTest][Discovery][WinUI3-Demo\WinUI3-UnitTests\bin\Debug\net5.0-windows10.0.19041\WinUI3-UnitTests.dll] Failed to discover tests from assembly WinUI3-Demo\WinUI3-UnitTests\bin\Debug\net5.0-windows10.0.19041\WinUI3-UnitTests.dll. Reason:File does not exist: WinUI3-Demo\WinUI3-UnitTests\bin\Debug\net5.0-windows10.0.19041\WinUI3-UnitTests.dll

在 MSTest output 日志中，它引發 System.InvalidOperation 異常

我的 Nuget 封裝供參考

    <PackageReference Include="Microsoft.Graphics.Win2D" Version="1.0.0.26-experimental1" />
    <PackageReference Include="Microsoft.ProjectReunion" Version="0.8.4" />
    <PackageReference Include="Microsoft.ProjectReunion.Foundation" Version="0.8.4" />
    <PackageReference Include="Vortice.WinUI" Version="2.0.20-beta" />
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.11.0" />
    <PackageReference Include="MSTest.TestAdapter" Version="2.2.7" />
    <PackageReference Include="MSTest.TestFramework" Version="2.2.7" />

Answer 1

通過將MSTest.TestAdapter和MSTest.TestFramework恢復到版本 2.2.3 解決。

Answer 2

我對 net6.0-windows10.0.19041 而不是 net5.0-windows10.0.19041 有同樣的問題。 （對比 2022 年）

將測試項目中的3個Nuget包升級到最新版本解決了。
