Gherkin BDD Runner

BDD Runner is a powerful Chrome side panel extension for writing and executing Gherkin BDD scenarios — no server, no CLI, no setup. Test REST APIs, automate browser interactions, and extend your tests with Lua scripting, all from a sleek editor built into your browser.

✨ FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📝 Full-Featured Gherkin Editor Write tests in familiar Given / When / Then format with a CodeMirror-powered editor that includes syntax highlighting, auto-indentation, and Tab support. Save and organize multiple feature files with the built-in file manager.

🌐 HTTP / API Testing Execute REST API requests directly from your scenarios — GET, POST, PUT, DELETE, PATCH. Set headers, query parameters, and request bodies. Validate responses with powerful assertions: exact match, contains, not-equal, and schema validation with type markers like #number and #string. Chain requests by capturing response values into variables with def.

🖥️ Browser Automation Control any web page using Chrome DevTools Protocol. Click, fill inputs, select dropdowns, check/uncheck boxes, press keyboard keys, wait for elements, scroll, and take screenshots — all from Gherkin steps. Use standard CSS selectors or accessibility tree selectors (e.g., button "Login", textbox "Username") for resilient, readable tests.

🔧 Lua Scripting Engine Go beyond built-in steps with inline Lua code. Parse JSON responses, run complex assertions, and capture computed values into variables. Create reusable custom step definitions with the Lua Script Manager — write a pattern once, use it across all your scenarios.
