As a developer i'll quit if I had to maintain code not tested... Naming convention on variables and functions is essential to me too, I use name casting to do so. If you follow your article you end with unmaintainable spaghetti code in my personal opinion.
Why quit? For me, it's a challenge to maintain code not tested. As one of my fellow architect said, "any code that isn't tested, is legacy code". Writing tests for legacy code it's one of my favorite parts of a project. I feel like a little Sherlock Holmes.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
