What problem does it solve? Writing and maintaining test suites for React/Next.js applications is time-consuming, and teams struggle to identify coverage gaps in critical paths like authentication and payments. This Skill automates test stub generation, coverage gap analysis, and E2E scaffolding so quality assurance work starts from a structured baseline instead of a blank file. ## Core Features & Use Cases - Test Suite Generation: Scans React/TypeScript components and generates Jest + React Testing Library test stubs with render, interaction, and optional accessibility (jest-axe) assertions. - Coverage Analysis: Parses Istanbul JSON or LCOV coverage reports, identifies uncovered lines and branches, flags critical paths (auth, payment, checkout), and enforces thresholds with a strict mode for CI pipelines. - E2E Scaffolding: Scans Next.js App Router or Pages Router directories and generates Playwright test files per route, plus optional Page Object Model classes, playwright.config.ts, and auth fixtures. - Use Case: After building a new Next.js dashboard, run the E2E scaffolder on src/app/ to generate Playwright specs for every route, then run the coverage analyzer against your Jest report to find untested payment logic before release. ## Quick Start Ask the assistant to generate Jest test stubs for all components in src/components and then analyze the coverage report at coverage/coverage-final.json with an 80 percent threshold.
