Behavior-Driven Development
Behavior-Driven Development (BDD) is an Agile software development philosophy that emphasizes collaboration between developers, QA engineers, and non-technical participants in a software project. The primary focus of BDD is on establishing a shared understanding of software requirements through writing clear, simple, and executable specifications expressed in natural language. These specifications take the form of user stories, which describe how the software behaves from the user's perspective. The BDD process typically involves three stages: Discovery, Formulation, and Automation. In the Discovery stage, team members explore and define the requirements using collaborative practices like Example Mapping. In the Formulation stage, they translate discovered examples into Gherkin scenarios. In the Automation stage, the scenarios are translated into step definitions and hooked up to actual implementation code. BDD helps in streamlining development, minimizes miscommunication, and ensures that software meets its intended purpose.
Guide to Behavior-Driven Development (BDD)
What is Behavior-Driven Development (BDD)?
Behavior-Driven Development (BDD) is a software development process that originated from Test-Driven Development (TDD). BDD involves writing tests that describe a behavior of the application, followed by the production code that makes the application behave as expected. The purpose is to help developers understand the requirements and the expected behavior of the systems they are developing.
Why is Behavior-Driven Development (BDD) important?
BDD not only helps clarify requirements but also becomes a form of communication between technical and non-technical participants in a project. It effectively bridges the gap between Business Analysts, Quality Assurance Engineers, and Developers, making the whole team capable of understanding how the application is expected to behave.
How does Behavior-Driven Development (BDD) work?
Behavior-Driven Development works by describing the behavior of a feature through a set of scenarios. Each scenario is a specific situation with defined inputs, actions and outputs.
