Behavior-Driven Development (BDD)

Simple Definition for Beginners:

Behavior-Driven Development (BDD) is a software development approach where the team writes tests based on the expected behavior of the application, making sure it meets the users’ needs.

Common Use Example:

A development team uses BDD to write tests in plain language that describe how a feature should work from the user’s perspective before they start coding.

Technical Definition for Professionals:

Behavior-Driven Development (BDD) is an agile software development process that encourages collaboration between developers, testers, and non-technical stakeholders. It extends Test-Driven Development (TDD) by writing test cases in natural language using a Given-When-Then format, which specifies the context (Given), the action (When), and the expected outcome (Then). BDD tests are often written in Gherkin syntax and executed using tools like Cucumber, SpecFlow, or Behave. This approach ensures that all team members have a clear understanding of the requirements and expected behavior of the application, resulting in higher-quality software that aligns closely with business goals.
