Test In Production: What Could Possibly Go Wrong?

The eternal battle between readable code and cryptic shortcuts! That one dev who insists on using x , tmp , and mgr instead of userAccountBalance , temporaryStorage , or connectionManager . Future maintainers will spend hours deciphering what bm.prc() does while the original author smugly thinks they're being efficient by saving 17 keystrokes. Bonus points if they also comment with "obvious function, no explanation needed." Clean code isn't just nice—it's practically a moral obligation. Your colleagues aren't mind readers, and neither is your future self at 2am during a production outage!

The sink works perfectly! The water flows through the faucet and... straight into the floor. Classic example of unit testing in software development – each component works flawlessly in isolation, but nobody bothered to check if they actually work together . The plumbing equivalent of "it works on my machine!" Sure, your authentication module passes all tests, but did anyone check if it actually talks to the database? This is why integration testing exists, folks – because passing unit tests is the programming equivalent of participation trophies.
