BDD vs Gherkin

Behavior Driven Development (BDD) is a software development process that aims to improve collaboration. It focuses on defining the behavior of the system from the user's perspective, using specifications written in natural language.

BDD evolved from Test Driven Development (TDD), with a more user-oriented approach towards the requirements and system behavior. This approach helps ensure that software development is better aligned with the expectations and needs of the end user.

The transition from TDD to BDD is characterized by a shift in focus from tests based solely on code to tests based on the system's behavior from the user's perspective. This facilitates a deeper understanding of the user's needs and how the system should behave to meet them.

BDD uses the Gherkin language to write specifications in a way that is understandable to both technical and non-technical team members. This allows the specifications to act as a shared source of truth, improving communication and reducing misunderstandings.

BDD promotes a shared understanding of the expected software behavior, ensuring that everyone involved, including non-technical stakeholders, has a clear understanding of the project's goals. This approach helps to avoid discrepancies between what the business needs and what the development team delivers.

Gherkin is a language used to specify the behavior of software systems in a way that is easy to understand for non-technical stakeholders.

It is particularly associated with Behavior-Driven Development (BDD) and is used to design test cases.

Gherkin has a specific syntax with keywords like Feature, Scenario, Given, When, and Then, which are used to structure test descriptions.

Gherkin is often used in conjunction with tools like Cucumber for test automation.
