/configure:ux-testing

Check and configure UX testing infrastructure with Playwright as the primary tool for E2E, accessibility, and visual regression testing.

When to Use This Skill

Use this skill when...	Use another approach when...
Setting up Playwright E2E testing infrastructure for a project	Running existing Playwright tests (use bun test:e2e or test-runner agent)
Adding accessibility testing with axe-core to a project	Performing manual accessibility audits on a live site
Configuring visual regression testing with screenshot assertions	Debugging a specific failing E2E test (use system-debugging agent)
Setting up Playwright MCP server for Claude browser automation	Writing individual test cases (use playwright-testing skill)
Creating CI/CD workflows for E2E and accessibility test execution	Configuring unit or integration tests (use /configure:tests)

Context

• Package manager: !find . -maxdepth 1 \( -name 'package.json' -o -name 'bun.lockb' \)
• Playwright config: !find . -maxdepth 1 -name 'playwright.config.*'
• Playwright installed: !grep -l '@playwright/test' package.json
• Axe-core installed: !grep -l '@axe-core/playwright' package.json
• E2E test dir: !find . -maxdepth 2 -type d \( -name 'e2e' -o -name 'tests' \)
• Visual snapshots: !find . -maxdepth 4 -type d -name '__snapshots__'
• MCP config: !find . -maxdepth 1 -name '.mcp.json'
• CI workflow: !find .github/workflows -maxdepth 1 -name 'e2e*'

UX Testing Stack:

• Playwright - Cross-browser E2E testing (primary tool)
• axe-core - Automated accessibility testing (WCAG compliance)
• Playwright screenshots - Visual regression testing
• Playwright MCP - Browser automation via MCP integration

Parameters

Parse from command arguments:

• --check-only: Report status without offering fixes
• --fix: Apply all fixes automatically without prompting
• --a11y: Focus on accessibility testing configuration
• --visual: Focus on visual regression testing configuration

Execution

Execute this UX testing configuration check:

Step 1: Fetch latest tool versions

Verify latest versions before configuring:

1. @playwright/test: Check playwright.dev or npm
2. @axe-core/playwright: Check npm
3. playwright MCP: Check npm

Use WebSearch or WebFetch to verify current versions.

Step 2: Detect existing UX testing infrastructure

Check for each component:

Indicator	Component	Status
playwright.config.*	Playwright	Installed
@axe-core/playwright in package.json	Accessibility testing	Configured
@playwright/test in package.json	Playwright Test	Installed
tests/e2e/ or e2e/ directory	E2E tests	Present
*.spec.ts files with toHaveScreenshot	Visual regression	Configured
.mcp.json with playwright server	Playwright MCP	Configured

Step 3: Analyze current testing state

Check for complete UX testing setup across four areas:

Playwright Core:

• @playwright/test installed
• playwright.config.ts exists
• Browser projects configured (Chromium, Firefox, WebKit)
• Mobile viewports configured (optional)
• WebServer configuration for local dev
• Trace/screenshot/video on failure

Accessibility Testing:

• @axe-core/playwright installed
• Accessibility tests created
• WCAG level configured (A, AA, AAA)
• Custom rules/exceptions documented

Visual Regression:

• Screenshot assertions configured
• Snapshot directory configured
• Update workflow documented
• CI snapshot handling configured

MCP Integration:

• Playwright MCP server in .mcp.json
• Browser automation available to Claude

Step 4: Generate compliance report

Print a formatted compliance report showing status for Playwright core, accessibility testing, visual regression, and MCP integration.

If --check-only is set, stop here.

For the compliance report format, see REFERENCE.md.

Step 5: Install dependencies (if --fix or user confirms)

# Core Playwright
bun add --dev @playwright/test

# Accessibility testing
bun add --dev @axe-core/playwright

# Install browsers
bunx playwright install

Step 6: Create Playwright configuration

Create playwright.config.ts with:

• Desktop browser projects (Chromium, Firefox, WebKit)
• Mobile viewport projects (Pixel 5, iPhone 13)
• Dedicated a11y test project (Chromium only)
• WebServer auto-start for local dev
• Trace/screenshot/video on failure settings
• JSON and JUnit reporters for CI

For the complete playwright.config.ts template, see REFERENCE.md.

Step 7: Create accessibility test helper

Create tests/e2e/helpers/a11y.ts with:

• expectNoA11yViolations(page, options) - Assert no WCAG violations
• getA11yReport(page, options) - Generate detailed a11y report
• Configurable WCAG level (wcag2a, wcag2aa, wcag21aa, wcag22aa)
• Rule include/exclude support
• Formatted violation output

For the complete a11y helper code, see REFERENCE.md.

Step 8: Create example test files

Create example tests:

1. tests/e2e/homepage.a11y.spec.ts - Homepage accessibility tests (WCAG 2.1 AA violations, post-interaction checks, full report)
2. tests/e2e/visual.spec.ts - Visual regression tests (full page screenshots, component screenshots, responsive layouts, dark mode)

For complete example test files, see REFERENCE.md.

Step 9: Add npm scripts

Update package.json with test scripts:

{
  "scripts": {
    "test:e2e": "playwright test",
    "test:e2e:headed": "playwright test --headed",
    "test:e2e:debug": "playwright test --debug",
    "test:e2e:ui": "playwright test --ui",
    "test:a11y": "playwright test --project=a11y",
    "test:visual": "playwright test visual.spec.ts",
    "test:visual:update": "playwright test visual.spec.ts --update-snapshots",
    "playwright:codegen": "playwright codegen http://localhost:3000",
    "playwright:report": "playwright show-report"
  }
}

Step 10: Configure MCP integration (optional)

Add to .mcp.json:

{
  "mcpServers": {
    "playwright": {
      "command": "bunx",
      "args": ["-y", "@playwright/mcp@latest"]
    }
  }
}

This enables Claude to navigate web pages, take screenshots, fill forms, click elements, and capture accessibility snapshots.

Step 11: Create CI/CD workflow

Create .github/workflows/e2e.yml with parallel jobs for:

• E2E tests (all browsers)
• Accessibility tests (Chromium only)
• Artifact upload for reports and failure screenshots

For the complete CI workflow template, see REFERENCE.md.

Step 12: Update standards tracking

Update .project-standards.yaml:

components:
  ux_testing: "2025.1"
  ux_testing_framework: "playwright"
  ux_testing_a11y: true
  ux_testing_a11y_level: "wcag21aa"
  ux_testing_visual: true
  ux_testing_mcp: true

Step 13: Report configuration results

Print a summary of configuration applied, scripts added, and CI/CD setup. Include next steps for starting the dev server, running tests, updating snapshots, and opening the interactive UI.

For the results report format, see REFERENCE.md.
