Keith Casey's Blog:
Bad Assumptions in Development
June 19, 2009 @ 12:04:28

No one's code is perfect, and if you think yours is - you're wrong. There'll always be something - might be logic errors or unhandled exceptions - that could cause issues later on. One of the worst problems, at least according to Keith Casey's recent post, is making too many assumptions.

In my opinion, the most annoying and worst for cleaning up the system are the functions/methods that make too many assumptions for you. It could be a variety of things - assuming a database connection, assuming what the output destination is, or assuming what the input is - but I most often see it in scrubbing/cleaning functions.

His example is a function that not only assumes that the type of input is correct but also returns the value via an echo rather than a return (despite the name of the function implying the second). As a follow-up, he also suggests that libraries/external tools don't make assumptions when it comes to stopping execution of the script either.
