Automation of testing in the business central [duplicate]

I am working on developing a project to automate the testing of my business central application (version 21). However, I am unable to include test libraries in the project at this time.

I adhered to the instructions in the manual and set up the business central version 21 sandboxes on docker.

Nevertheless, I am unable to access any test library references. This is my application. json:

        "includeSourceInSymbolFile": true
    },
    "runtime": "10.0",
    "features": "NoImplicitWith"
}

here is the error:
