Benefits of Test Driven Development (TDD)

1: Developer plays the role of user and developer while writing code, hence customer centric approach throughout the development 2: Reduces real time issues because of code written with end user mindset 3: Initially takes time but overall less-n-less debugging time 4: Identify cascading code break early or related change in other modules 5: Regression fix early 6: Help avoiding over engineering code which we don’t need actually 7: Avoid Scope Creep, helps in design and create high possibility of acceptance
