Gherkin is a plain-language syntax for writing .feature files that describe software behavior. BDD practices use Gherkin's Given-When-Then structure to translate requirements into executable scenarios, enabling living documentation and shared understanding between technical and non-technical stakeholders.

Yes. Gherkin .feature files can be linked to test automation using Python or JavaScript frameworks. BDD practices support optional automation that connects scenario steps to code, turning specifications into executable tests while maintaining readable documentation.

BDD extends TDD by starting with human-readable scenarios written in Gherkin before code. Where TDD writes tests in code, BDD clarifies requirements through feature files first, then optionally automates them. This keeps specifications, tests, and documentation aligned throughout development.

Gherkin .feature files serve as living documentation that stays current with code. BDD practices guide discovery and formulation phases to produce executable or review-only specifications. Feature files act as both requirements and runnable tests, reducing documentation drift.

BDD works well for scenarios with clear user interactions and expected outcomes. Login flows and CRUD operations are concrete enough to express in Given-When-Then format. BDD practices provide templates and phase-driven guidance to extract these scenarios from requirements consistently.

Gherkin excels at user-facing workflows but can become verbose for complex business logic or data-heavy operations. BDD practices include red-flag guidance to prevent anti-patterns—over-automation of non-BDD logic or scenarios too technical for stakeholder review reduce the value of living documentation.
