[Debichem-devel] Bug#1061601: openstructure: FTBFS with Python 3.12 as default

Hi Maintainer

openstructure FTBFS with Python 3.12 as the default version (i.e. with
python3-defaults/3.12.1-1 from experimental).  I've copied what I hope
is the relevant part of the log below.

Python 3.12 now returns 5 instead of 0 when all tests in a unit test
are skipped.  This is the case for test_sec_struct.py when
debian/patches/skip-dssp-tests.patch is applied.

I was able to work around this by adding a dummy test:

--- a/modules/mol/alg/tests/test_sec_struct.py
+++ b/modules/mol/alg/tests/test_sec_struct.py
@@ -6,6 +6,9 @@

 class TestSecStruct(unittest.TestCase):

+  def testDummy(self):
+    return
+
   @unittest.skip("Incompatible with dssp >= 4")
   def testSecStruct(self):

Regards
Graham
