What is BDD?
Behavior-Driven Development
The development process of defining how software should behave in simple sentences that everyone can understand.
Overview
BDD enables non-technical people to be involved in the software development process. It focuses on what the user will do and how the system will react, rather than the technical details of the software. Thanks to this method, developers and business units speak the same language.
How it works
First, the expected behavior of the system is written as 'If the user does X, outcome Y should occur'. These sentences are then coded and tested. If the code meets this behavior, the software is working correctly.
Where it is used
It is used in software projects, especially in the development of complex features and to reduce the margin of error.
Commonly confused with
Can be confused with TDD; While TDD focuses on the robustness of the code, BDD focuses on the behavior of the function in the eyes of the user.
