#2 - TDD vs BDD vs ATDD : Key Differences

#TDD vs #BDD #ATDD
In this video, I have explained the key differences between TDD (Test Driven Development), BDD (Behavior Driven Development) and Acceptance Test Driven Development) approaches.

Test-driven development (TDD) is a technique of using automated unit tests to drive the design of software and force decoupling of dependencies. The result of using this practice is a comprehensive suite of unit tests that can be run at any time to provide feedback that the software is still working.

ATDD stands for Acceptance Test Driven Development, it is also less commonly designated as Storytest Driven Development (STDD). It is a technique used to bring customers into the test design process before coding has begun. It is a collaborative practice where users, testers, and developers define automated acceptance criteria. ATDD helps to ensure that all project members understand precisely what needs to be done and implemented. Failing tests provide quick feedback that the requirements are not being met. The tests are specified in business domain terms. Each feature must deliver real and measurable business value: indeed, if your feature doesn’t trace back to at least one business goal, then you should be wondering why you are implementing it in the first place.

Behavior-Driven Development (BDD) combines the general techniques and principles of TDD with ideas from domain-driven design. BDD is a design activity where you build pieces of functionality incrementally guided by the expected behavior. The focus of BDD is the language and interactions used in the process of software development. Behavior-driven developers use their native language in combination with the language of Domain Driven Design to describe the purpose and benefit of their code.

Hi Naveen, I have been following you for quite some time now. It would be good if your camera doesn't keep moving. Some people who have medical conditions cant concentrate on these types of videos. Thanks

[ssrinivasulu]

Thanks Naveen for the insight.
But do have a specific questions related TDD:
1. Why TDD is called Developer Centric Approach ?
2. And why not a Test Centric Approach ? ( We are writing the tests first after understanding the requirement)
3. Do we have any Example of a Test Centric Approach.

[JitendraKumar-lrvq]

Hi Naveen can we have videos on cucumber 6 and serenity bdd ..which has very good features..and also about updated videos on rest assured..

BDD is an improvement of TDD, refer to Dan North how and why he developed BDD basis in TDD, ATDD as Specification by Example are just other ways to name BDD
