What I run into, over and over again, is code that can't be executed in isolation. I mostly work in Java, and I keep ending up maintaining codebases where nearly everything is declared "static"... including the code that connects to databases and remote services and initializes data to start the service. I've seen this "pattern" across four different employers over two decades now.
