TestLeft support for UI-testing of "VisualStudio Extensions" - Ready to use? HowTo?

Thanks for your reply.

I just mentioned that I like to test VisualStudio Extensions because that is my main domain.

I can not test an VisualStudio Extension when the test tooling (i.e. TestLeft) does not support the application barebone. You have to know that most menus and toolbar are weaved dynamically during runtime (i.e. base on a xml-dialect called VSCT [Visual Studio Command Table, see https://docs.microsoft.com/en-us/visualstudio/extensibility/internals/visual-studio-command-table-dot-vsct-files?view=vs-2019]. We provide several commands with our VisualStudio Extension as well some individual toolwindows and several editor implementations, etc.pp.

Anyway, we like to have UI-testing for integration-tests (i.e. blackbox tests) with a "release" setup of our VisualStudio Extension. In this case we have a minimum set of debug information. We do some reflection and we use "Automation Interface"-approaches (e.g. EnvDTE.*) but 50-75% can be visual checks (e.g. screenshot compares, color checks, etc.) We do not need any VisualStudio-insides.

After said this, the easiest way to check if any test tooling allow UI-testing for VisualStudio is, to just clarify if the basic menu-walks work, e.g. go to Menu | File | New… to create a new project. When this does not work any effort to handle other calls will not work as well and the test tooling is not usable for our scenarios.

Currently I do not know how to traverse any dynamically weaved (vsct-based) UI-elements in VisualStudio, here for example, to create a new project (see attached screenshot).

Currently I tried three ways to query the menu item "Project...":

using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using SmartBear.TestLeft.TestObjects;
using SmartBear.TestLeft.TestObjects.WPF;

namespace TestLeftProject1
{
    [TestClass]
    public class TestLeftTest : UnitTestClassBase
    {
        #region Class initializers
        [ClassInitialize]
        public static void ClassInitialize(TestContext context)
        {
            UnitTestClassBase.InitializeClass(context);
        }

        [ClassCleanup]
        public static void ClassCleanUp()
        {
            UnitTestClassBase.FinalizeClass();
        }
        #endregion

        private IProcess _process = null;

        private IProcess RunVisualStudio()
        {
            if (_process == null)
            {
                _process = Driver.Applications.Run(
                @"C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\Common7\IDE\devenv.exe",
                @"/rootSuffix Exp");
            }

            var proc = System.Diagnostics.Process.GetProcessById(_process.ProcessId);
            if(proc.HasExited)
            {
                _process = null;
                _process = RunVisualStudio();
            }

            return _process;
        }

                try

                    {
                        ClrFullClassName = "Microsoft.VisualStudio.PlatformUI.MainWindow"
                    }, 2);

                    if (mainWindow == null)
                    {
                        System.Threading.Thread.Sleep(500);

                        continue;
                    }

                    mainWindow.Keys("ctrl+shift+n");
                }
