Does not work

[programuotojasgf]

Does not work - either Theory or Fact, does not matter. Using latests xUnit.

Could you add an example, so I could test this on a premade project, to be sure it's my fault somehow?

.csproj:

<PackageReference Include="Meziantou.Xunit.ParallelTestFramework" Version="2.3.0" />

Tests.cs:

using Meziantou.Xunit;

public class ImmutableClass
{
}

[CollectionDefinition(nameof(SomeCollection))]
[EnableParallelization]
public class SomeCollection : ICollectionFixture<ImmutableClass>
{
}

[Collection(nameof(SomeCollection))]
[EnableParallelization]
public class TestClass1
{
    [Fact]
    public async Task Test1() => await Task.Delay(3000);

    [Fact]
    public async Task Test2() => await Task.Delay(3000);
}

[Collection(nameof(SomeCollection))]
[EnableParallelization]
public class TestClass2
{
    [Fact]
    public async Task Test3() => await Task.Delay(3000);

    [Fact]
    public async Task Test4() => await Task.Delay(3000);
}
