Creating mock data for software testing

I really like coding. And i really like improve my knowledge about design pattern and new architecture. I started at 13 just thirty one years ago ( self taught ) when I bought my first Sinclair ZX Spectrum. Nowadays I am a Senior Software ( Agile ) Engineer with more than 18 years of experience in Enterprise Application design and development, both back-end and front-end.
I am particularly interested in Enterprise Design Pattern, Domain Driven Design, Test Driven Design and Scrum Methodology, looking for new patterns in software development
I do not want to keep my learnings to myself, so I had joined code project, and adding few more learnings which may benefit many other software engineers and developers working in this lovely industry. I'm not going to dictate any of the points, but all the practices listed here contributed a lot in my software development career, so if you think they make some sense for you then try to adopt few. If you have any +/- comments, kindly feel free to write me back
