Playwright QA

Purpose

Automated visual QA testing for web applications. Uses Playwright to launch a headless browser, navigate the app like a real user, take screenshots, check for console/network errors, test interactive elements, verify responsive layouts, and identify visual bugs — then fix them automatically.

Routing

• Use when: Any web app task that mentions testing, catching bugs, verifying it works, shipping, or quality — even without explicitly mentioning Playwright or visual QA. Also use when the user builds a web app and the implicit expectation is that it should work.
• Do not use when: The task is purely about unit tests, API testing, non-web application testing, or native mobile app testing.
• Outputs: QA report with checks (passed/failed), issues categorized by severity, screenshots, and interaction log.
• Success criteria: All checks pass, or issues are identified with clear descriptions and auto-fixed where possible.

Trigger Examples

Positive

• Build a todo app in React, test it to catch any bugs before shipping
• Build a dashboard and make sure it works
• Create a landing page and verify everything looks right
• Build this web app and ship it bug-free
• Make a React app, test it
• Build a weather app and check for issues
• Create the app and QA it
• Build and test the frontend
• Does the app work?
• Test this web app with Playwright
• Run visual QA on localhost:3000
• Check my site for bugs
• Do automated browser testing
• Verify the UI works
• Screenshot and test the web app
• Find visual bugs in my project
• Test the app like a real user
• QA the frontend
• Run Playwright tests
• Make sure it works before we ship

Negative

• Write unit tests with Jest
• Run jest/vitest tests
• Test the API endpoints with curl
• Do load testing with k6
• This is a native iOS/Android app
• Run backend unit tests

Parameters

| Name | Type | Required | Description | | -------------- | ------ | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- | | url | string | No | Target URL to test (defaults to http://localhost:3000) | | server_command | string | No | Command to start the dev server (e.g., "npm run dev") | | checks | string | No | Comma-separated list of checks: visual_snapshot, console_errors, network_errors, interaction_test, responsive_check, accessibility_check, performance_check |

Runtime Prompt

You are running automated visual QA on a web application using Playwright.

**Workflow:**

1. **Install dependencies** (if project was just scaffolded):

• If the project has a `package.json` but no `node_modules`, run `npm install` (or `yarn`/`pnpm install`) via `run_command` first.
• NEVER skip this step for a freshly created project — `npm run dev` will fail without it.

2. **Start the dev server** (if not already running):

• Use `qa_run` with `server_command` to start it automatically, OR
• Use `run_command` to start the server manually if needed

3. **Run full QA pipeline**:

• Call `qa_run` with the target URL and enabled checks
• This will automatically: launch browser, navigate, check console errors, check network errors, take visual snapshots, and test interactive elements

4. **Review results**:

• Check the QA report for any issues
• Issues are categorized as critical, major, or minor

5. **Fix issues** (if auto_fix is enabled):

• For each critical/major issue, fix the code
• Re-run `qa_run` to verify the fix
• Repeat until all critical/major issues are resolved

6. **Manual testing** (for specific flows):

• Use `qa_navigate` to go to specific pages
• Use `qa_interact` to test user flows (click buttons, fill forms, hover elements)
• Use `qa_screenshot` to capture state at key points
• Use `qa_check` to run specific checks

7. **Cleanup**:

• Always call `qa_cleanup` when done

**Key tools:**

• `qa_run` — Full automated pipeline (recommended starting point)
• `qa_navigate` — Navigate to a URL
• `qa_interact` — Click, fill, hover, scroll
• `qa_screenshot` — Take a screenshot with diagnostics
• `qa_check` — Run a specific check
• `qa_report` — Get current run report
• `qa_cleanup` — Tear down browser and server

**Best practices:**

• Always start with `qa_run` for a comprehensive first pass
• Fix critical issues before minor ones
• Re-run after fixes to verify
• Use `qa_interact` for specific user flow testing
• Take screenshots at key interaction points
• Check both desktop and mobile viewports
