What does this skill do?

The Senior QA Testing Engineer skill helps an agent build comprehensive test automation for React and Next.js applications.

It combines unit and integration testing with Jest and React Testing Library, E2E testing with Playwright, coverage analysis, and accessibility checks.

It ships helper scripts to generate test stubs from components, analyze coverage gaps, and scaffold Playwright E2E tests, with coverage targets by project type.

  • Generates Jest test stubs from React components

  • Scaffolds Playwright E2E tests for Next.js routes

  • Analyzes coverage and flags critical untested paths

  • Adds accessibility assertions with jest-axe and axe-core

How it works

1

Generate component tests

The agent scans React/TypeScript components and generates Jest test stubs with render, interaction, and accessibility patterns.

2

Scaffold E2E tests

It scans the Next.js app and generates Playwright E2E tests per route, with optional Page Object Model classes.

3

Analyze coverage

It parses coverage reports, identifies critical untested paths like auth and payments, and enforces thresholds.

4

Integrate CI/CD

It provides GitHub Actions templates for automated testing, coverage reporting, and E2E validation.

Best use cases for this skill

  • Component testing: Generate Jest test stubs for React components.

  • E2E setup: Scaffold Playwright tests for a Next.js app.

  • Coverage gaps: Find and prioritize critical untested paths.

  • Accessibility: Add automated accessibility checks to the suite.

Frequently asked questions

What does the Senior QA skill do?

It provides test-automation infrastructure for React and Next.js — Jest and Playwright test generation, coverage gap analysis, E2E scaffolding, and accessibility checks.

When should an agent use it?

Use it to set up testing infrastructure, generate component or E2E tests, analyze coverage gaps, or add accessibility testing for a React/Next.js project.

Which tools does it use?

Jest and React Testing Library for unit and integration, Playwright for E2E, Istanbul/NYC for coverage, MSW for API mocking, and jest-axe for accessibility.

What coverage targets does it use?

Targets scale by project type — for example higher line, branch, and function coverage for production and enterprise projects than for an MVP.
