Can I set DoNotParallelize or Parallelize in csproj

[johnthcall]

As part of upgrading to MSTest 4 my projects are getting flagged with mstest0001 and I do not have runsettings files or assemblyInfo files to add this to and instead of choosing a random test file to add it to I was wondering if there is any way to set this in the csproj itself.

You have at least three options:

• Add <NoWarn>$(NoWarn);MSTEST0001</NoWarn>
  • This can be done in individual csproj files, or centrally via Directory.Build.props.
• You can enable parallelization via:

  •   <ItemGroup>
        <AssemblyAttribute Include="Microsoft.VisualStudio.TestTools.UnitTesting.Parallelize">
          <_Parameter1>Workers = 0</_Parameter1>
          <_Parameter1_IsLiteral>true</_Parameter1_IsLiteral>
          <_Parameter2>Scope = Microsoft.VisualStudio.TestTools.UnitTesting.ExecutionScope.MethodLevel</_Parameter2>
          <_Parameter2_IsLiteral>true</_Parameter2_IsLiteral>
        </AssemblyAttribute>
      </ItemGroup>

• You can disable parallelization via:

  •   <ItemGroup>
        <AssemblyAttribute Include="Microsoft.VisualStudio.TestTools.UnitTesting.DoNotParallelize" />
      </ItemGroup>

Alternatively, you can also use the MTP json (assuming you are using it): https://learn.microsoft.com/dotnet/core/testing/unit-testing-mstest-configure#parallelism-settings

@Evangelink That won't be considered by the analyzer though.
