Assembles a multi-step end-to-end user-journey test from a list of high-level user intents - translates each intent ("user signs up", "user adds product to cart", "user completes checkout with promo code") into the corresponding test-runner step (Playwright / Cypress / Selenium / Karate), wires shared state across steps via test fixtures, and emits the resulting test as a single Scenario in the project's E2E framework. Use when scaffolding an E2E test that exercises a complete user flow rather than a single page.
