testing-nonfunctional-suite（测试非功能性套件）

Non-Functional Test Suite

Run comprehensive non-functional testing covering performance, security, accessibility, and other quality attributes.

When to use me

Use this skill when:

• Preparing applications for production deployment
• Validating quality attributes beyond functionality
• Complying with performance SLAs or security standards
• Testing under realistic load and stress conditions
• Ensuring inclusive design and accessibility
• Validating deployment and operational readiness

What I do

1. Performance Testing

- Load testing with expected user traffic - Stress testing to find breaking points - Endurance testing for memory leaks - Scalability testing for growth planning

1. Security Testing

- Vulnerability scanning and penetration testing - Authentication and authorization testing - Input validation and injection testing - Security configuration review

1. Accessibility Testing

- WCAG compliance validation - Screen reader and keyboard navigation testing - Color contrast and visual accessibility - Assistive technology compatibility

1. Compatibility Testing

- Cross-browser and cross-platform testing - Mobile device and responsive design testing - Network condition simulation

1. Usability Testing

- User experience evaluation - Navigation and workflow testing - Error message clarity and helpfulness

Examples

# Run non-functional test suite
npm run test:nonfunctional       # Custom non-functional suite

# Performance testing
npm run test:performance
npx autocannon -c 100 -d 60 https://app.example.com

# Security scanning
npm run test:security
npm audit
npx snyk test

# Accessibility testing
npm run test:accessibility
npx pa11y https://app.example.com

# Compatibility testing
npm run test:compatibility
npx playwright test --browser=all

Output format

Non-Functional Test Suite Results:
──────────────────────────────
Performance (Load: 1000 users, 10 minutes):
  ✅ Response Time: Avg 320ms (target < 500ms)
  ✅ Throughput: 2.1k req/sec
  ⚠️ CPU Usage: 92% (near limit)
  ✅ Error Rate: 0.05%

Security Assessment:
  ✅ No critical vulnerabilities found
  ⚠️ 3 medium severity issues
  ✅ Dependencies up to date
  ⚠️ Missing security headers (CSP, HSTS)

Accessibility (WCAG 2.1 AA):
  ✅ 42/58 criteria passed
  ⚠️ 12 criteria partially met
  ❌ 4 criteria failed (color contrast, form labels)

Compatibility:
  ✅ Chrome, Firefox, Safari (latest)
  ⚠️ Edge: Minor layout issues
  ✅ Mobile: iOS & Android responsive

Usability:
  ✅ Navigation intuitive
  ⚠️ Error messages could be clearer
  ✅ Forms accessible and clear

Overall: Meets most non-functional requirements
Priority Fixes: Accessibility issues, security headers

Notes

• Non-functional requirements are often overlooked but critical
• Establish clear acceptance criteria for each quality attribute
• Test in environments as close to production as possible
• Consider user demographics for accessibility testing
• Security testing should be ongoing, not one-time
• Performance testing should include realistic user behavior patterns
• Document non-functional requirements alongside functional ones
• Automate regression testing for non-functional aspects where possible
