While I think your suggestion is the proper solution I do not think that
it is worth the effort. I would rather do the following:
1. Exclude those test that are failing (it is only a small number)
for the architectures where the test fails). Please do not hesitate
to ask here if you are lacking ideas how to do this. May be the
python-cogent package can serve as an exemple. Its probably
sufficient to do something like this:
override_dh_auto_test:
ifeq ($(BUILDARCH),...)
mkdir tempdir
mv test/... tempdir
endif
dh_auto_test --sourcedirectory=test
dh clean --sourcedirectory=test
ifeq ($(BUILDARCH),...)
move back files to restore original source state
rmdir tempdir
endif
2. Since you have saved time to work out proper tests on rarely
used architectures you have time to package
https://github.com/bioinfo-ut/GenomeTester4
While the later is half joking this could be quite useful. You would
have need the tool for your original plan - may be for other things as
well and you could learn packaging.
Kind regards
Andreas.
