Few days ago I have an experience with setting CCNet build server for continues integration environment. What is it continues integration and why you need to know it you can learn from many articles, and the better of course is article written by Martin Fowler. Also you can read a book Continuous Integration: Improving Software Quality and Reducing Risk, which Martin Fowler advises well.
Below I will try to tell you main steps of setting continues integration environment and will give you some advices. Also I will glad to look response and advices from you. So, what is it continues integration? In this case word integration mean integration not across some systems (applications), as you can think when you will heart this phrase first time (this was my case). In this case this word means integration across team members.
