Please Don't Be My Code I Promise To Unit Test Next Time

That sinking feeling when you're on-call and production goes down, and you start reading through the stack trace only to see familiar function names from that "quick fix" you pushed last week. You know, the one you shipped without tests because "it's just a small change, what could go wrong?"

Now you're literally in a hole, praying to the tech gods that it's someone else's garbage code causing the outage. But deep down, you already know. That's YOUR NullPointerException. That's YOUR uncaught promise rejection. That's YOUR brilliant idea to refactor the entire authentication flow at 4 PM on a Friday.

Every developer makes the same bargain: "Just let this one slide and I swear I'll write tests for everything from now on." Spoiler alert: they never do. The cycle continues until the next incident call.
