I will need more time to properly fix these errors.

Initially I only wanted to update cryptography to the latest version but then bumped into other issues with pytest.

[sebastian-luna-valero]

ok, fixed.

However, does anyone have better ideas to avoid these mocks and improve the testing?

Thanks!
