Problem with pybuild and pytest (repost)

[Ole Streicher <olebole@debian.org>]

Hi,

I already posted this two weeks ago, but didn't get a response yet, and
thus it remains unsolved:

For one of my packages (sunpy), I want to complete the switch to pybuild
by removing the custom (and quite unperfect) dh_override_auto_test rule.

Currently, I have the following lines in d/rules:

override_dh_auto_test:
	python -m pytest sunpy -k "not figure and not online"
	python3 -m pytest sunpy -k "not figure and not online"

This gives successfull tests with the following output in the log:


--------------------------8<-------------------------------------------

>From the pybuild wiki page, I learned to do instead the override:

export PYBUILD_TEST_ARGS=-k "not figure and not online"

However, then the tests are not found anymore and the test step fails:


--------------------------8<-------------------------------------------
   dh_auto_test -O--buildsystem=pybuild
I: pybuild base:217: cd /build/sunpy-0.9.3/.pybuild/cpython2_2.7_sunpy/build; python2.7 -m pytest -k "not figure and not online"

dh_auto_test: pybuild --test --test-pytest -i python{version} -p 2.7 returned exit code 13

I don't understand why the tests fail now? How do I correctly specify
them?

Best regards
