Neat!  I like it too, I’d say we can go frmo here.

Heh.  :-)

Could it be because the file it tries to open here is read-only?

Usually files resulting from a checkout are read-only, so perhaps you
need to make a bunch of files writable before the ‘check’ phase.  For a
start you could do:

  (for-each make-file-writable (find-files "tests"))

Once you’ve sorted that out I’m happy to publish if there are no
objections!

Thanks,
Ludo’.
