.NET Core 与 NUnit 测试

Question

I'm using .NET Core and am creating a unit test.

To do this, I'm running "dotnet new nunit -n tests" to create a project with the first class to test another project.

The problem is: I can run the simple code created with "dotnet test", but I can't code because I'm receiving 'could not be found NUnit' error.

PS.: I'm using Visual Studio Code (last version).

My .csproj:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>

    <IsPackable>false</IsPackable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="nunit" Version="3.11.0" />
    <PackageReference Include="NUnit3TestAdapter" Version="3.11.0" />
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.9.0" />
  </ItemGroup>

</Project>

The error:

The type or namespace name 'NUnit' could not be found (are you missing a using directive or an assembly reference?)

Answer 1

I solved the problem using Visual Studio 2017 (not Visual Studio Code). It is better to architect a Microsoft solution.

EDIT : If you are using Visual Studio (complete version) you can see better the solution, projects and references.

If you are using Visual Studio Code and include new class or files, the reference is not added in you project file (.csproj) automatic. Maybe have another way to do that, but in the moment, I just use the complete version.

Answer 2

I ran into this issue too and was perplexed by it. It turns out the problem is with the solution, not the dotnet new nunit project that was created.

The solution is auto-including the sub directory and attempting to build it as source. The directory can be excluded by right clicking the new test project in the solution and selecting "Exclude from Project". Rebuild and the errors go away.
