Nextjs Testing
This skill should be used when writing or setting up tests for a Next.js application. Trigger when: configuring Vitest, Cypress, or Playwright for Next.js; writing unit tests for components or hooks; writing E2E tests; testing React Server Components; testing API routes or Route Handlers; testing Server Actions; setting up test infrastructure; choosing between testing tools; implementing data-testid attributes; testing authentication flows; mocking API responses with cy.intercept() or page.route(); troubleshooting test failures; testing with production builds; or asking about Next.js testing best practices, patterns, or anti-patterns.

From the source SKILL.md
Next.js blurs the line between frontend and backend. Relying on unit tests alone is insufficient — E2E tests are essential for catching bugs at the client/server intersection.
What this skill does
Nextjs Testing is a community-contributed Claude Code skill in the frontend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/nextjs-testing/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Nextjs Testing Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the Nextjs Testing skill?
Use Nextjs Testing when your Claude Code task falls under the Engineering category — specifically in the frontend area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Nextjs Testing" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the Nextjs Testing skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Nextjs Testing is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category. Learn more at
