Gauntlet Test Unable to find test in assemblies 5.4

Hello all:

I am trying to use Gauntlet for a simple test like a helloworld kind of approach, i have setup a C++ testcontroller .cpp and .h and a HelloworldText.cs also added Gauntlet in Build.cs file of my project.

I could run the command to cookandrun that looked kind of like this

.\RunUAT.bat BuildCookRun -project=D:\UE\HelloWorldTestAuto\HelloWorldTestAuto.uproject -noP4 -platform=Win64 -clientconfig=Development -serverconfig=Development -cook -build -stage -pak -archive -archivedirectory=D:\UE\HelloWorldTestAuto\BuildWin

Build is succesfull in this step, but when i run this command to run my test

.\RunUAT.bat RunUnreal -project=D:\UE\HelloWorldTestAuto\HelloWorldTestAuto.uproject -platform=Win64 -build=D:\UE\HelloWorldTestAuto\BuildWin -test=HelloWorldTest

The command fails after some time with

Unable to find type HelloWorldTest in assemblies. Namespaces=Gauntlet.UnrealTest, UnrealGame, UnrealEditor.

Can someone help me or point me into what i am missing?

Thanks in advance and Best Regards

That command will work only if the .cs project you made is within the Engine. If it is in your project, you must also include the -scriptdir= argument leading to your root project folder, like so:
-scriptdir=D:\UE\HelloWorldTestAuto
