[Debian-astro-maintainers] Bug#966713: astropy test fails

[Drew Parsons]

Source: astropy
Version: 4.0.1+post1-3
Severity: normal

astropy has started failing tests.  Failure is triggered by scipy
1.5.2-2, but tests passed with scipy 1.5.2-1.

The details of the failure don't appear to be related to scipy.
It involves Leap_Second.dat instead:


___________ TestDefaultAutoOpen.test_system_file_used_if_not_expired ___________

self = <astropy.utils.iers.tests.test_leap_second.TestDefaultAutoOpen object at 0xffff77360370>
tmpdir = local('/tmp/pytest-of-debci/pytest-0/test_system_file_used_if_not_e0')

    @pytest.mark.skipif(not os.path.isfile(SYSTEM_FILE),
                        reason=f'system does not have {SYSTEM_FILE}')
    def test_system_file_used_if_not_expired(self, tmpdir):
        # We skip the test if the system file is on a CI and is expired -
        # we should not depend on CI keeping it up to date, but if it is,
        # we should check that it is used if possible.
        if (iers.LeapSeconds.open(SYSTEM_FILE).expires <= self.good_enough
                and ON_CI):
            pytest.skip("CI system leap second file is expired.")
    
        self.remove_auto_open_files('erfa')
        with iers.conf.set_temp('system_leap_second_file', SYSTEM_FILE):
            ls = iers.LeapSeconds.open()
            assert ls.expires > self.good_enough
>           assert ls.meta['data_url'] in (iers.IERS_LEAP_SECOND_FILE,
                                           SYSTEM_FILE)
