Frequently Asked Questions
What are Claude Code skills for testing?
Claude Code skills for testing are SKILL.md files that teach Anthropic Claude Code (the official CLI agent) how to write tests using specific frameworks like Playwright, Cypress, pytest, JUnit, or k6. Each skill ships expert patterns, locator strategies, fixture setups, and assertion conventions so Claude writes production-quality tests on the first try.
How do I install a Claude Code testing skill?
Run `npx @qaskills/cli add <skill-name>` in your project. The CLI auto-detects Claude Code and writes the skill to `~/.claude/skills/<skill>/SKILL.md` (global) or `<repo>/.claude/skills/<skill>/SKILL.md` (project). Claude picks it up on the next session.
Which testing skills work best with Claude Code?
Highest install counts are playwright-e2e, cypress-e2e, selenium-advance-pom, pytest-patterns, jest-unit, react-testing-library, k6-performance, api-testing-rest, and testcontainers-postgres. All work seamlessly with Claude Code 1.0+.
Do these skills work with Claude Desktop or only Claude Code?
These are designed for Claude Code (the CLI). Claude Desktop uses a different skill format. For Desktop, use the Anthropic Skills marketplace. QASkills.sh specifically targets the coding agents that read SKILL.md files (Claude Code, Cursor, Copilot, Windsurf, etc.).
Are Claude Code skills free?
Yes. All skills on QASkills.sh are MIT licensed and free. Some advanced skill packs are available as premium bundles, but the core skills cover every major testing framework at no cost.
Can I write my own Claude Code testing skill?
Yes. See /how-to-publish: create a SKILL.md, validate with `npx @qaskills/skill-validator`, publish with `npx @qaskills/cli publish`. Your skill becomes installable by every QASkills.sh user within 30 seconds.
