In my experience, if you mention to people there's not enough testing, most of them will agree. They've probably been fighting that fight for a long time. Cut your team some slack. Before you go telling them they're doing it wrong, do better yourself. Make sure your code is well tested. When doing code reviews, request more tests strategically. (Meaning, don't complain that there are no tests. Point out specific tricky or dangerous areas where an extra test could make a difference). If they don't know how, help them. ASK about current practices ("Hey, is there a style guide I can use to help me get up to speed?"). DON'T tell them you know better. If you make them resent you from the beginning, you'll never make any progress.
