Thanks, your patch looks good to me. And the two test functions work in
general.

Just some few comments:

Please give it another name, which comes lexically before
tramp-test46-unload. That test must be the last one, because it unloads
Tramp in batch mode.

I recommend tramp-test44-dired-compress-file.

"compresses"

Add also

  (skip-unless (tramp--test-sh-p))

This is the only backend which implements dired-compress-file.

Same comments.

If you like you could push it to Emacs, I will run then the zillions of
test configurations I have available locally.

Thanks, and best regards, Michael.
