Re: testutils + GitHub action -> fail

Hi Claude

I must admit I haven't got any idea. I've just checked out RAT's master
(the PR has been merged) and the test worked fine on my Ubuntu machine.

I see you have disabled the test by now, but in my case GITHUB_ACTION is
not set so the test is executed.

Cheers
