Where can I find statistics / figures on how long testing should / could take?
- by NoCarrier
I'm trying to convince management that testing/QA takes considerably longer than non-developers think.  Some smaller shops don't have budgets for testers and phbs automatically assume the developer will spend a few minutes after every build "testing" and deliver a perfectly functional system.  
Can someone point me to some numbers? e.g. Testing should be XX% of your total man hour count , etc etc?  Or perhaps some real world experience?  My goal is to have some numbers that are grounded in real life so I can make time/effort allocation justifications for "proper" testing when preparing estimates and timelines for applications.  Maybe not full blown 100% TDD, but pragmatically close to it.
I apologize if I seem vague.
