'I possess the only truth and you need to prove me wrong not the other way around'. I witness this so often I'm starting to believe it's the motto of the software industry. The drift to fundamentalism about TDD over the last years is just another example. TDD is a good methodology that can save time and improve code quality, but only if understood and performed correctly. That means more unit tests does not equal a better design and easier to maintain code base produced in less time. Better unit tests, testing non trivialities and accepting the limitations of unit testing does. You cannot possibly test all states on a sufficiently complex, non trivial program constantly evolving to better fit its users' needs as they are discovered and redefined. And that's not the basis of TDD: Outlining your design by identifying its fundamental parts and writing tests for them before implementing them is. Back to the main topic, I have seen people rant about version control systems, integrated developing environments and all kinds of tools and procedures involved in the software development process: They all take a few good arguments and stretch them to irrationality. For example: how can somebody like git and HATE mercurial, bazaar... Maybe you prefer one or the other and you have your reasons, that's alright: Different tools for different people. But am I a dumb person for having different preferences? And if I'm not, does that mean you are dumb? I've seen pretty dumb things done by developers using every tool/methodology, including myself. Usually the reason is their lack of experience and understanding, much more often than using the wrong tool/methodology. TDD or whatever, once you learn you'll do fine. But don't be an asshole and blindly criticize people who prefer doing it differently, even if you are the smarter one. Specially if you are the smarter one. And just because you don't understand a tool or methodology (yet, or ever) it doesn't mean people using it are dumb, that's all I'm saying. TDD has been proven effective. TDD hasn't disprove all other effective approaches out there. Specially the ones yet to be discovered by less arrogant people.
