What is test driven development? in the process of development, test will be implimented for each stage in order to keep the development process in control. It is quite interesting concept.


The Wikipedia defines it as follows:


Test-driven development (TDD) is a software development process relying on software requirements being converted to test cases before software is fully developed, and tracking all software development by repeatedly testing the software against all test cases. This is as opposed to software being developed first and test cases created later.

Software engineer Kent Beck, who is credited with having developed or "rediscovered"[ the technique, stated in 2003 that TDD encourages simple designs and inspires confidence.

Test-driven development is related to the test-first programming concepts of extreme programming, begun in 1999,[ but more recently has created more general interest in its own right.[

Programmers also apply the concept to improving and debugging legacy code developed with older techniques.
