There is some merit to concerns about the culture on Stack Exchange. Just like on Wikipedia, you can run into some rando småpåve who thinks they’re the king of the world and tries to put you in your place while they’re the one who’s being all wrong about something.

It sucks when that happens, but overall I think Wikipedia and especially Stack Exchange have been successes, especially in the context of the ephemerality of Usenet and IRC.

In a nutshell, Agile in game development means dividing the process of game creation into short iterations. Thus, instead of working on the whole project from the very beginning to the release, the development team works on small projects which are normally called features. 

As developers write code, they can build unit testing modules directly into the code to ensure that by the time a piece of software has moved through the DevOps lifecycle, it has already been tested against most scenarios. If done correctly, this is a very efficient way to test code. Building testing modules into code requires that a fair process is in place to ensure that testing occurs throughout the entire process. Once done, this module can perform some of the duties required from a QA tester.  

Symflower automatically generates and runs high coverage unit tests for your source code, revealing bugs and security issues while you are coding.
