The difference between BDD and ATDD is that BDD is a development method where everyone has to test every feature of the product and give feedback on it. In contrast, A-TDD is a method where the developers only get feedback on their feature in the form of acceptance tests.

Difference Between BDD and ATDD

What is BDD?

Behavior Driven Development (BDD) is a development method that involves the use of acceptance tests. The idea behind BDD is to produce software with a higher quality by providing the developers with continuous feedback. BDD is an evolution of Test-Driven Development (TDD).

In the beginning, TDD was used as a tool to provide feedback to developers on their code as they were writing it. But as time went on, TDD was also used to produce acceptance tests and give feedback on them. With BDD, you can have both tests and feedback at the same time, which can help in improving quality in your product and decrease the time taken for development.

What is ATDD?

Acceptance Test Driven Development (ATDD) is a software development method that involves the use of acceptance tests. The idea behind ATDD is to produce software with a higher quality by providing the developers with continuous feedback. ATDD is an evolution of Behavior Driven Development (BDD).

In the beginning, BDD was used as a tool to provide feedback to developers on their code as they were writing it.

BDD VS ATDD

Behavior Driven Development is a development method where everyone has to test every feature of the product and give feedback on it. In contrast, ATDD is a method where the developers only get feedback on their feature in the form of acceptance tests. Behavior Driven Development has one developer per test class.

BDD and ATDD are similar because they both test every feature of a product and provide continuous feedback to developers. In addition, BDD and ATDD both require one developer per test class. The main difference between these two methods is that in BDD, everyone has to test every feature of the product whereas in A-TDD only developers need to test their feature in the form of acceptance tests.
