MSTest 2.2.4+ does not runs tests contained in classes with non alphanumeric characters in the class name

[sylvainouel]

This works fine with MSTest.TestAdapter and MSTest.TestFramework 2.2.3, but the test is skipped with 2.2.4 or 2.2.5.

module x.TestProject1

open System
open Microsoft.VisualStudio.TestTools.UnitTesting

[<TestClass>]
type ``babette la morue`` () =

    [<TestMethod>]
    member this.TestMethodPassing () =
        Assert.IsTrue(true);

I get the following output from dotnet test:

PS C:\Users\souellet\source\repos\TestProject1> dotnet test

I can reproduce the issue. Looks like the space is causing issue.

This is not linked to the test ID generation but was linked to a bug in hierarchy processing. Updating our object model dependency fixed the issue.

I will close the issue and confirm fix will be included in v3.
