The Joel Test is now considered to be obsolete because it awards points for things like "Do you have testers?" and "Do you fix bugs before writing new code?", which aren’t considered best practices by most devs today.
Can anyone explain why having testers isn't considered a best practice by most devs today?
Devs should be testing their own stuff too, of course.
Only to check that it's actually working before sending it off to the testers. Unit tests can be a good way to do this.
Make no mistake though: a good tester is worth their weight in gold because they will find many "real life" edge cases the developer would not have thought about, as well as UX issues if the feature being tested is user-facing.
I probably would be disinclined to hire a developer who wanted a different person to write/run their tests, unless it was for a very specialized role and said developer had exceptional talents.
That's not the role of the tester. The developer should be writing and running their own unit tests. The Tester should be running through user scenarios, use cases, and basically be pretending to be a user of the software to make sure that everything works and makes sense in a workflow (not just in their unit components)
