Have you by chance changed the version of Python you were running the test suite against between two runs? If I remember correctly the sqlite database is not always cleaned up and a previous test run on Python3 might for example leave behind a database file that contains data stored in a format that Python2.7 doesn't understand.

That might be the problem. Where is that database so that I can remove it before the run?

mcepl commented 5 years ago

Yes, rm -fv tests/test.db helped, but still I think it is a bug in your test suite, that it doesn't clean up after itself.

amol- commented 5 years ago

Yeah, that needs to be addressed, but is not a major priority because in fact the test suite handles this fine. The problem only arises if you try to switch python environments.
