Class level [Parallelizable(ParallelScope.None)] not overriding Assembly level [assembly: Parallelizable(ParallelScope.Fixtures)]?

[Jeremy Dunn]

I have two test fixtures I am looking to run serially. Since most of my other tests run in parallel I have the assembly attribute set to parallelize. From what I gather in the documentation(https://github.com/nunit/docs/wiki/Parallelizable-Attribute). setting the class level attribute to ParallelScope.None should override the assembly level attribute for any fixtures contained in that class, right? Here's some simplified code:

{AssemblyInfo.cs}:

...
[assembly: Parallelizable(ParallelScope.Fixtures)]

...

{MyTests.cs}:

[Parallelizable(ParallelScope.None)]
public class MyNBTests
{
     [TestFixtureSource(typeof(MyTestFactory))]
     public class MyTest1 : BaseTestClass
        {
            //Test method
        }
 

    [TestFixtureSource(typeof(MyTestFactory))]
    public class MyTest2 : BaseTestClass
        {
            //Test method
        }
}

If I move the attribute onto each test individually, it works as I expect:

public class MyNBTests
{

    [Parallelizable(ParallelScope.None)]
    [TestFixtureSource(typeof(MyTestFactory))]        
    public class MyTest1 : BaseTestClass
       {
           //Test method
       }

    [Parallelizable(ParallelScope.None)]
    [TestFixtureSource(typeof(MyTestFactory))]
    public class MyTest2 : BaseTestClass
        {
           //Test method
        }
}

Should I not expect a parent class' attribute to override the children [TestFixture] classes?

Historically, NUnit has never treated nested classes in any special way. For example, selecting the outer class doesn't cause the nested classes to be run. So what you're seeing is consistent even if surprising. We have talked about treating nested classes as subtests but nothing has been implemented.
