dotnet test will only run existing MSTest, and not include new xUnit test

Here's what my Test project .csproj looks like:

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

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>

    <IsPackable>false</IsPackable>

    <RootNamespace>MyProject.WebAPI.Test</RootNamespace>
  </PropertyGroup>

All existing tests in this project are MSTest, they have attributes like [TestClass] at the class level and [TestMethod] at the unit test method level.

I introduced an xUnit test class to test a controller, and ran dotnet test, but it does not recognize my new xUnit test class / 1 test method in it, with [Fact] attribute.

How can I make dotnet test recognize and run both xUnit and MSTest tests? Am I missing a package?

Solution 
  • <PackageReference Include="xunit.runner.visualstudio" Version="2.4.3">
  <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
  <PrivateAssets>all</PrivateAssets>
</PackageReference>

    Added this to my MyProject.WebAPI.Test.csproj and then ran dotnet test, it worked!
