A practical AI task guide

How to auto-test your web app with AI

The answer

Use the webapp-testing skill (Playwright toolkit) to drive and verify a local web app from your AI agent.

3 steps

Step 1: Add the Anthropic skills marketplace in Claude Code

/plugin marketplace add anthropics/skills
/plugin install example-skills@anthropic-agent-skills

Step 2: Or copy the skill folder into your project

mkdir -p .claude/skills
git clone --depth 1 https://github.com/anthropics/skills.git /tmp/anthropics-skills
cp -R /tmp/anthropics-skills/skills/webapp-testing .claude/skills/webapp-testing

Step 3: Ask your agent to use webapp-testing on a local app

Use the webapp-testing skill to open my local app and verify the main user flow.

Author's take / 作者点评

Solid Playwright-based webapp testing guidance that worked end-to-end locally. Great for agents writing UI checks; avoid networkidle waits.

本地 Playwright 端到端可用，适合让代理写 UI 测试；别死等 networkidle。
