E2E Test Scenario Quality Review

Systematic checklist for reviewing E2E spec files AND Page Object Model (POM) files. Covers Playwright and Cypress with full grep + LLM analysis. General principles (name-assertion alignment, missing Then, YAGNI) apply to any framework, but automated grep patterns are Playwright/Cypress-specific.

Phase 0: Framework Detection

Before running checks, enumerate candidate source files with the scanner's exact extension set: .ts, .js, .tsx, .jsx, .mts, .mjs, .cts, and .cjs. Inspect actual import statements and cy. calls in those files to determine the framework:

• @playwright/test → Playwright
• cypress (as a module import or cy. call) → Cypress
