Unit Test Mock Objects Segmentation Faults

Hey guys,

I found an article about mocking the database for unit testing: https://www.rami.me.uk/how-to-unit-test-code-with-phalcon-mvc-models/

Unfortunately, I've been getting segmentation faults. Specifically when the model tries to save. I've never really used gdb but did a backtrace I believe. Is this an issue with codeception/phpunit or phalcon? I've had a lot of trouble mocking and/or using fixtures. Anyone have any experience or resources they'd like to share?

Trying to test validation (UserTest::testValidation) ...
