What Is BDD?

Test-driven development (TDD) involves writing tests before writing code to drive the development process, while behavior-driven development (BDD) focuses on describing the expected behavior of the software through natural language specifications. TDD is more developer-centric, whereas BDD emphasizes collaboration between developers, testers, and nontechnical stakeholders in software development.

Behavior-driven development (BDD) frameworks, such as Cucumber or SpecFlow, enhance collaboration between developers and nontechnical stakeholders. They use natural language specifications, making requirements more accessible, and provide automated tests that validate whether the software meets these specifications.

Behavior-driven development (BDD) practices include collaborative scenarios, automated acceptance criteria, and living documentation. BDD emphasizes clear communication among development, testing, and business stakeholders using a common language.

BDD principles include collaboration between development and business teams, writing tests in plain language (Given-When-Then), and using these tests as specifications for development, ensuring a shared understanding of requirements.

Behavior-driven development (BDD) is implemented by defining scenarios using natural language, creating step definitions, and using tools like Cucumber or SpecFlow to automate tests based on these scenarios.
