python-mnemonic: problem with test not able to find local file

[Soren Stoutner]

I am in the process of updating python-mnemonic. Historically, tests have not
been enabled. I can build the new version just fine, but when I enable tests
by adding a Build-Depend on "python3-pytest <!nocheck>” the build fails [1]
E FileNotFoundError: [Errno 2] No such file or directory: 'vectors.json'
tests/test_mnemonic.py:45: FileNotFoundError

vectors.json is located in the root [2]. But for some reason it is not
available in the test environment (or the test is looking in the wrong place).
I could, of course, disable the tests again. But I would like to run them if
possible. Does anybody have any idea what I would need to do to make this file
available to the test?

Hi,

the file must not have been copied to the testbed, I assume. You can try adding a debian/pybuild.testfiles file with vectors.json listed in it and that'd *probably* take care of the issue.

Best,

that's one option and mostly the more straightforwarded one.

I often use this different way. The comments are not needed, just added
to show what is happen here.

BTW:
If you do a 's/dh-python/dh-sequence-python3' in d/control you can also
drop the '--with python3' option in the default rarget in d/rules.

Thank you to everyone for your help. This fixed the problem.

Thank you. I had seen dh-sequence-python3, but I was unaware of what using it
would do.
