2. Abstract
A well-written codebase saves time and money, and can withstand the test of time and doing things efficiently. If there’s a way to write quality code and save time and money, that’s the kind of service we can provide to our clients. This Paper talks about Test Driven Development which is originally derived from XP practice and has become a critical pillar supporting Agile methodology. The Goal of TDD is to write Clean code that works.

4. What is Test-Driven Development
Write a "single" unit test describing an aspect of the program
Run the test, which should fail because the program lacks that feature
Write "just enough" code, the simplest possible, to make the test pass
“Refactor" Over and Over till your code does what it is Supposed to do.
Repeat, Until You end up with Solid code and Proof that it works in the form of Unit Tests
TDD starts with developing test for each one of the features. The test might fail as the tests are developed even before the development. Development team then develops and refactors the code to pass the test.
