Core Methodology

• Accessibility Standards: WCAG 2.1/2.2, Section 508, ADA, EN 301 549
• Accessibility Principles: Perceivable, Operable, Understandable, Robust
• Assistive Technologies: Screen readers, voice recognition, screen magnifiers, alternative input devices

Output Format Requirements

## Accessibility Testing Plan: [Product Name]

### Testing Overview
- **Product Type:** [Web Application/Mobile Application/Desktop Application]
- **Compliance Standards:** [WCAG 2.1 AA/AAA, Section 508, ADA]
- **Target Users:** [Visual/Auditory/Motor/Cognitive impaired users]
- **Testing Focus:** [Compliance verification/User experience/Assistive technology compatibility]

### WCAG 2.1 Compliance Testing

#### Four Principles Testing
| Principle | Testing Focus | Verification Method | Priority |
|-----------|---------------|-------------------|----------|
| Perceivable | Text alternatives, contrast, captions | Automated+Manual | P0 |
| Operable | Keyboard navigation, focus management | Manual testing | P0 |
| Understandable | Clear content, error handling | Manual verification | P1 |
| Robust | Code semantics, compatibility | Automated scanning | P1 |

#### Key Success Criteria
- **1.1.1 Non-text Content:** All images have alt text
- **1.4.3 Contrast (Minimum):** Text contrast ≥ 4.5:1
- **2.1.1 Keyboard:** All functionality supports keyboard operation
- **3.1.1 Language of Page:** Correctly identify page language
- **4.1.2 Name, Role, Value:** Correct use of ARIA attributes

### Automated Testing

#### Tool Configuration
```javascript
// axe-core automated testing
const { AxePuppeteer } = require('@axe-core/puppeteer');

describe('Accessibility Tests', () => {
  test('WCAG 2.1 AA compliance', async () => {
    await page.goto('http://localhost:3000');
    
    const results = await new AxePuppeteer(page)
      .withTags(['wcag2a', 'wcag21aa'])
      .analyze();
    
    expect(results.violations).toHaveLength(0);
  });
});

Manual Testing

Keyboard Navigation Testing

Test Scenario: Complete core tasks using keyboard only

Test Steps:
1. Use Tab key to navigate all interactive elements
2. Verify focus order is logically reasonable
3. Check focus indicators are clearly visible
4. Test keyboard shortcut functionality
5. Verify modal dialog keyboard traps

Verification Points:
- [ ] All functionality accessible via keyboard
- [ ] Tab order follows visual layout
- [ ] Focus indicators clearly visible
- [ ] No keyboard trap issues
- [ ] Shortcuts work normally

Screen Reader Testing

Test Tools: NVDA (Windows) / VoiceOver (Mac/iOS)

Test Scenario: Browse page using screen reader
1. Start screen reader
2. Use H key to browse heading structure
3. Use Tab key to browse interactive elements
4. Test form filling and submission
5. Verify error message reading

Verification Points:
- [ ] Page titles and heading structure clear
- [ ] All content can be read correctly
- [ ] Links and buttons have descriptive text
- [ ] Form controls have associated labels
- [ ] Error messages clear and understandable

Mobile Device Testing

iOS VoiceOver Testing

Test Scenario: Browse mobile app using VoiceOver
1. Enable VoiceOver functionality
2. Use swipe gestures to navigate
3. Test double-tap activation functionality
4. Verify rotor control functionality
5. Test voice control

Verification Points:
- [ ] All elements have accessibility labels
- [ ] Gesture navigation smooth and natural
- [ ] Voice feedback clear and accurate
- [ ] Rotor functionality works normally

Issue Classification and Fixes

Issue Severity

Severity	Definition	Fix Priority	Examples
Critical	Prevents users from completing core tasks	P0	Missing alt text, keyboard inaccessible
Important	Affects user experience but not blocking	P1	Insufficient contrast, incorrect heading structure
General	Minor impact on user experience	P2	Link text not descriptive enough
Minor	Optimization suggestions not affecting functionality	P3	Page language not identified

Test Report

Compliance Assessment

• WCAG 2.1 AA Compliance Rate: [X%]
