Gherkin Validator

The Gherkin Validator analyzes feature files to verify syntax, keyword usage, and step references. It targets developers, testers, and BDD teams who author scenarios in cucumber-like DSLs. By feeding raw Gherkin text or a .feature file, users receive precise diagnostics and line-level feedback, enabling faster iteration and higher-quality feature suites. The tool supports standard English keywords and common dialects used in modern acceptance test suites.\n\nConceptually, it parses the input into a lightweight abstract syntax tree, validates grammar against the Gherkin specification, cross-references steps with defined step implementations, and flags undefined, duplicate, or unreachable steps. It also checks tag usage, scenario ordering, and feature-level structure. The validator can operate in real time as you type or on-demand for larger batches, returning a structured result set suitable for automation.\n\nWho benefits: QA engineers validating acceptance criteria, automation engineers maintaining step libraries, product owners ensuring scenario coverage, and teams incorporating BDD into CI/CD pipelines. By surfacing exact locations of errors and suggested fixes, it reduces debugging time and improves collaboration between non-technical and technical stakeholders.\n\nCore value lies in reproducible checks, exportable reports, and CI-friendly outputs. Use cases include verifying new feature files before review, auditing existing suites for consistency, and integrating validation into pull request checks. Advanced users can enable batch validation across repositories and generate JSON reports for downstream tooling.
