Unit Tests Don't Find Bugs: the Death of QA

[Terrence Dorsey]

DZone[^]:

TDD's goal is to prevent programmers from introducing new bugs into working code. However, when you're writing code from scratch, your tests won't help you find all the bugs in your code. That's because you can't possibly write tests for all the ways your software will be used (or abused). When I first started doing TDD, I had really good tests, but I was too tired to do much exploratory QA. However, my boss wasn't, and I was very embarrassed to find that my software had lots of bugs. Simply put, he used my software in ways that I hadn't intended.

Worked on my machine (as long as I didn't actually click anything).

They are releasing products with only unit testing? That sounds suicidal

This makes my heart sink. Will we ever find a fool-proof way to find bugs? Not to mention the amount of time it takes to create unit tests.

From a logical perspective; no, not ever. It's also not helpful to aim at something like that, it's more appropriate to expect mistakes.

Bastard Programmer from Hell :suss: if you can't read my code, try converting it here[^]

You're right.
