TDD vs BDD vs ATDD: Analyze the Key Differences

We all know that the technology revolution is at its peak and pandemics give it more sparks. Being in the field of software development, you must keep moving with the new frameworks, tools, languages and processes that keep changing every day.

Writing workable code is the second thing. But before you must think about what, how, when and for what purpose you are writing code. Developers give their day in and out to write robust code.

But have you ever wondered what methodologies drive the developers and their creations to writing the code. Some great methodologies include TDD vs BDD vs ATDD.

Let’s discuss.

Test-driven Development - TDD

It is the methodologies to develop the test case before developers start writing the code. As per the requirement of the software, these test cases are just a small unit.

Here the approach is to continually test the written code through a “red green refactor loop” and the test has been done until it is absolutely ready to become a part of the scheme.

We also wrote about the laws and characteristics of the TDD in our original article.

Behavior-driven Development - BDD

It is the Next version of TDD. If every unit of the app functions as per its need to be, then this method tests.

Here in the next version of TDD, functional level tests rule out the code which is unnecessary for max functionality of the app.

We also discuss the major characteristics of BDD in the article.

Acceptance Test-driven Development - ATDD

It is the combination of TDD and BDD. These techniques keep focusing on the demands of the users and give their best to meet the requirements. It is also known as Story Test-driven development.

ATDD approaches get together various stakeholders like developers, testers, and customers. It is crucial that those stakeholders need to share the common understanding of users' needs.

We also discuss the major characteristics of ATDD in the article.

In our article, we compare them with various factors such as their purpose, Participants, Preferred Language, Tests, Bugs, Suitability, and Preferred Tools. Our comparison will help you to understand which methodology you need to choose. If you want to know in more detail about TDD vs BDD vs ATDD, read our article now.
