It shows lack of experience to suggest having a gap in testing is somehow "recklessly ignoring industry standards". If you look at Symfony's test suite it's clear that they take testing extremely seriously and keep their tests up to date in a way that's far superior to my experience with "industry standard". If you look at the fix for this issue which is linked from the OP you'd see that the first thing they did is add a unit test to prevent this kind of issue from happening again. If you consider that kind of behavior recklessly unprofessional I'd be amazed to see the kind of tests you write for your code.
