DirectoryNotFoundException when using test runner in a Standalone build

Hey guys,

when testing my game, I need to read some files, which are placed in the same folder as the scripts of my playmode tests.

1. By clicking on "Run All" in the Unity Test Runner everything works fine.

2. By clicking on "Run All Tests (Standalone Windows 64) in the Unity Test Runner I get a DirectoryNotFoundException in my tests logs
   
   A temporary folder was made for the tests in the test build but there is no reference to Asset folder path. So the questions is:

How to reference files in a Standalone test build for the rest runner?

I'm using Unity 2019.4 and the test runner package 1.1.30.

Thanks for your help!
