Show HN: Cypress Copilot: AI Plugin for Cypress automation code generation (github.com)

Cypress Copilot is a new Visual Studio Code extension that generates Cypress BDD test code—step definitions and Page Object Models (POM)—from Cucumber-style scenarios using AI. The plugin claims to outperform GPT-3.5, GPT-4 and GitHub Copilot for BDD code by producing fewer syntax problems and broader code coverage, and it uses a novel Few-shot Chain Prompting approach (described in an associated IEEE paper). It integrates directly into the VS Code command palette, supports multiple OpenAI models, provides real-time code previews, and is published on the VS Code Marketplace. Technically, the extension requires VS Code, Node.js, Cypress installed in your project, and a Cucumber preprocessor for Cypress. Users must supply an OpenAI API key (session persistence may be flaky) and paste BDD scenarios to generate code; outputs are editable but not guaranteed correct, and the extension accepts only BDD-format input. Important caveats: don’t submit PII/PHI, review generated tests before use, and expect model inconsistency across edge cases—switch models if results vary. The project is open source (license details in repo) and aimed at streamlining Cypress + Cucumber E2E workflows for teams wanting AI-accelerated test scaffolding.
