by Mike Bria on  Feb 14, 2008 7

Peter Ritchie raised concern about TDD and BDD keeping practitioners from writing good unit tests. He cites an over-reliance on “interaction testing", a core mantra and essence of TDD and BDD, as a driver with tendency to result in incomplete unit testing.

Separating business logic from technology: Kathleen Dollard on a new view of code generation

by Sadek Drobi on  Dec 21, 2007 8

Even the most successful project becomes a failure when a new technology comes out and everything has to be rewritten from the ground. This is why business logic has to be separated from technology. And, according to Kathleen Dollard, code generation is a promising approach to achieve it.

Test Driven Development or Test Driven Requirements?

by Amr Elssamadisy on  Nov 20, 2007 27

Where does one start when practicing test driven development? With the requirements or with the design? Or, put another way, top-down or bottom-up?

User-Centric Development Approaches: What's Next?

by Deborah Hartmann Preuss on  Feb 12, 2007 3

On her Creating Passionate Users blog, Kathy Sierra recently envisioned software that's not just usable, but transparent, helping users achieve "flow" in their work without intrusive distractions, delays or constraints. Perhaps end-user "flow" is the next big differentiator - and if so, what will the development processes look like that support the creation of such software?

by Pat Eyler on  Nov 30, 2006 1
