Interview with Robert C. Martin (Uncle Bob)
The VKSI Magazine is having an interview with software craftsmanship legend Bob Martin (@unclebobmartin).Interviewers:Dr. Susann Mathis (VKSI Magazine)Marc P...
■ Interviewer : it's often what managers say is that clean code is too expensive or kind of the forward writing tests that cover all the code.
■ Robrt C.Martin : [Laugh] I would respond that I can make it as cheap as you'd like and deliver it on any schedule you want as long as it doesn't have to work !
And actually it's not managers saying that. You might find some low-level managers saying stuff like that but you talk to the CEO of a company you ask that CEO "you thought you want your software to be high quality?" and he's gonna say "what I thought that it already was of course ! I want it to be high quality I'm betting my business on it !"
The little manager off in the corner who's worried about the schedule is going to say something silly like "oh oh we don't really have time to write tests". Of course you've got time to write tests you don't have time not to write tests. How much debugging do you want to do? how much chasing down horrible bugs? do you want to do or correcting corrupted databases?
