Behavior-driven development (BDD)
What is behavior-driven development (BDD)?
Behavior-Driven Development (BDD) is an agile software development methodology that encourages collaboration between developers, testers, and business stakeholders to ensure that software meets the expected behaviors and requirements. It focuses on the desired behavior of the application from the user's perspective, rather than just technical specifications.
BDD uses simple, natural language to define application behavior in the form of scenarios, often written in the Given-When-Then format:
Given (the initial context)
When (an action or event)
Then (the expected outcome)
These scenarios act as a shared understanding between all parties involved in the development process, promoting communication and reducing ambiguity. BDD frameworks, like Cucumber or SpecFlow, allow these behaviors to be directly linked to test automation, enabling automated execution of tests to ensure the software works as expected. BDD thus helps improve the quality, transparency, and maintainability of software while ensuring that it aligns with user needs and expectations.
