Primary focus of this article is to get a brief introduction of programming methodology of Test Driven Development

Programming software in way that comprises on high standards of responsiveness to the change of requirement and extreme quality coding. This methodology is called the extreme Programming or XP and TDD Test Driven Development is the first step in achieving XP programming standards. TDD uses test cases to be developed before the coding starts and these test cases to be passed for each functionality of the program.

Test Driven Development revolves around three things Testing, Coding and the Design or refactoring. What to do when you write one function that is not an appropriate usage for the other code in the program. Is not better to write code which is as perfect for each step of the program.

Test driven Development saves you a lot of time and makes your development a breeze. It brings a flow coding making each step concise and clear.

Some time it is also called the TFD Test First Development.

Acceptance Test Driven Development ATDD

It is the Test Driven Development which involves with planning and setting of goals to be achieved prior to start of programming. Tests are developed initially and the coding begins after this. This collaborative work, all time discusses about and present examples to be achieved through tests. It is also called the behavior development.

There are involved steps of planning the requirement, development of tests and applying it to code and performing a demo of implantation of tests.

Unit Test and Developer TDD

Developer crafts testing codes called unit tests before writing the actual code of the program. Than these unit tests are effectively used in on small coding steps of the actual program making advancement in the program more efficiently.

Benefits of Test Driven Development

Making use of Test Driven Development is of great importance and it assure the production of a program more efficient and accurate in timely manner with less bugs and issues as each code chunk is integrated into the program after passing the specific test.

It also helps developer to gain a level of satisfaction as pass a tests mean code is written well.
