Just because unit testing existed in the 90s, it doesn't mean it was widely (ab)used as it is now! Many technologies were invented well before they gained adoption. I didn't mean unit testing is new or useless - just that it's being abused ignoring the benefit-cost ratio and negatively affecting you thought process to rely on something unreliable instead on focusing on code quality - tests are no panacea as code today is more tested than ever, but is also buggier than ever as well. As a summary: Just think more when you write code, don't get into the vicious circle of try-refresh-repeat, and having tests in place is no excuse for poor code.
