Please also revert changes to poetry.lock

@cunla All requested changes have been applied, I believe the PR should be ready for another (or final) review round 🙂

Tests fail on py3.7 (see checks).
@the-wondersmith not sure if you got the previous message.. notice the checks - some scenarios fail

[the-wondersmith]

@cunla I saw it, just didn't have time in the day to get to it yesterday. I'll get it fixed up and re-pushed shortly.

EDIT: @cunla Fixed, pushed. 😁

Still failing.. checkout the workflow logs

[the-wondersmith]

@cunla Completely forgot I had act installed. I'll run the workflows locally till they pass and let you know.

For the tests with redis-py < 4 - use the decorator to skip your tests:

@testtools.run_test_if_redispy_ver('above', '4.2.0')

[the-wondersmith]

@cunla Knew I missed something when I stripped out hypothesis from the tests. Drat! 😅

Fixed and pushed.

@the-wondersmith Please squash and merge
