Bug Impossible to run PlayMode tests grouped by namespace

Hello,

I have spotted what seems to be a regression when upgrading the test framework from 1.1.24 to any more recent version. The project I am working on is using Unity 2019.4.28f1
To reproduce this:
- Create a test directory as explained in the documentation
- Create directories inside there to organise some tests
- For each Script inside of a folder, make them part of a namespace with the corresponding name (in my example, it is Tests.Namespace1 or Tests.Namespace2)
- Create some [UnityTest] in each script
You should have an arborescence looking like the screenshot below :




Now, right-click on a namespace listed in the TestRunner, and click on Run. The tests will be ignored.
With the version 1.1.24, I have a normal behavior and tests are run.

 

So temporary workaround is to flatten Namespace and leave files structure unchanged, while renaming classes to single class splitted among files with "partial" keyword. Is that so?

Taking example above, it would be:
NewTestScript1.cs with "public partial class NewTestScript{}" and namespace Tests/Namespace1
NewTestScript2.cs with "public partial class NewTestScript{}" and namespace Tests/Namespace1
