Hello,
Thank you for this batch file.

Is this line needs correction?
Manually add the .TcPOU files to the _MyProject\_Tests_ project

Like this?
Manually add the .TcPOU files to the _MyProject_Tests\Plc\POUs

Thanks @kumaraswamygaviyappa! Nice catch.

If the batch file is executed for the second time, Error is generated: A file cannot be created if it already exists.

Yes that is correct. You only have to link a file once.
