Gherkin acceptance criteria

Gherkin is a domain-specific language using structured natural language to define executable test cases through Given-When-Then keywords.

Gherkin transforms ambiguous requirements into precise behavioral specifications. By utilizing a restricted vocabulary (keywords like Feature, Scenario, and Background), it bridges the communication gap between developers, QA engineers, and business stakeholders. This format serves a dual purpose: it acts as living documentation for the system and provides the foundational scripts for automation frameworks like Cucumber or SpecFlow. Teams using Gherkin reduce rework by identifying edge cases during the discovery phase before a single line of application code is written.
