What problem does it solve? End-to-end tests often pass for the wrong reasons, fail for environmental reasons, or cannot be debugged from CI, making them liabilities instead of protection. This Skill reviews E2E test diffs with a strict evidence standard so every test actually proves the user-visible behavior it claims to protect. ## Core Features & Use Cases - Requirement Drift Detection: Verifies that final assertions prove the stated acceptance criterion or regression rather than incidental details, mocks, or page arrival. - Structured Category Sweep: Audits selector contracts, synchronization, isolation, secrets handling, and CI trust as blockers, plus locator quality, data setup, diagnostics, and CI economics as concerns. - Framework-Aware Judgment: Applies real Playwright and Cypress semantics such as auto-waiting locators, command queuing, and isolation defaults to avoid false findings. - Use Case: A teammate opens a PR adding Playwright tests for a checkout flow. Run this review to catch hard sleeps, order-dependent state, and assertions that prove navigation instead of the business outcome before merge. ## Quick Start Review this Playwright test diff for requirement proof, selector stability, synchronization, isolation, and CI reliability using the e2e-review standard.
