Errors in testing

Hey!
I decided to keep your package in the Debian project. It is already under analysis. Soon it will be in the official distribution repositories.
As dependencies undergo constant updates, Debian uses "tests" as a verification tool to find out whether the codes have not been affected by any update.

And cetvalidator is showing errors in tests, both at build time and isolated with "pytest".

Below are the two records for investigation.

Start by running pytest and reviewing tests/test_certificate_validator.py, tests/test_crl_client.py, tests/test_ocsp_client.py, tests/test_registry.py, and tests/test_validate.py. Investigate the reported certificate path-building and expired-intermediate failures; done means the affected tests pass without masking the validation errors.
