As you see the test data is missing. So one would need to re-create it for importing it into
the new tarball.

For this particular package, there is a script which can do this for you, but I actually
had to change it a bit (pushed to salsa, please pull).

This is what I did:

$ cd debian/tests/

$ ./get-test-data

CMU-1-Small-Region.svs
removed 'CMU-1-Small-Region.svs'
Now move openslide_3.4.1+dfsg.orig-debian-tests-data.tar.xz next to the new upstream tarball and gbp import it as usual

$ mv openslide_3.4.1+dfsg.orig-debian-tests-data.tar.xz ../../..

$ cd ../..

$ uscan -dd

$ gbp import-orig --pristine-tar ../openslide_4.0.0+dfsg.orig.tar.xz

gbp:info: Replacing upstream source on 'master'

Hope this helps. If you are still stuck, please ask.

PS: uscan does have support for MUT, by using groupsources, but we'd need an upstream tar for that along with a regex.
Hence we will need to go about manually for this case. If there are better ideas, happy to hear.

Thanks,
Nilesh
