What We Test
Comprehensive automated testing across all WCAG success criteria
Perceivable
Information and UI components must be presentable to users
- ✓Text alternatives for non-text content
- ✓Captions and alternatives for multimedia
- ✓Content structure and presentation
- ✓Color contrast ratios (4.5:1 for normal text, 3:1 for large text)
- ✓Use of color alone to convey information
Operable
UI components and navigation must be operable
- ✓Keyboard accessibility (all functionality via keyboard)
- ✓Focus indicators and tab order
- ✓Sufficient time to read and use content
- ✓Seizure and physical reaction prevention
- ✓Navigable page structure and landmarks
Understandable
Information and UI operation must be understandable
- ✓Readable text with language identification
- ✓Predictable navigation and functionality
- ✓Input assistance and error identification
- ✓Form labels and instructions
- ✓Error suggestions and prevention
Robust
Content must be robust enough for assistive technologies
- ✓Valid HTML and ARIA markup
- ✓Name, role, and value for all components
- ✓Status messages and live regions
- ✓Compatibility with current and future assistive technologies
- ✓Semantic HTML element usage

Why Traditional Tools Miss 43% of Issues
Static code analysis tools like axe-core, WAVE, and Pa11y are excellent for detecting markup-level issues, but they fundamentally cannot test what requires a real browser environment.
Behavioral Testing
Static tools check if elements exist, but cannot test how they actually work when users interact with them.
Example: Modal focus traps, escape key functionality, and focus restoration require actual keyboard interaction
Content Quality Evaluation
AI must judge whether content is truly accessible—not just technically compliant but genuinely usable.
Example: Generic link text like "click here", error messages that just say "Error", or alt text that says "image"
Context-Aware Assessment
Accessibility depends on context. AI evaluates whether implementations make sense for the specific use case.
Example: Tab order that is technically valid but illogical for the user flow, or ARIA usage that is correct but confusing
User Experience Testing
Beyond compliance, AI assesses whether the experience is actually good for users with disabilities.
Example: Keyboard navigation that works but feels unnatural, or screen reader announcements that are confusing
Semantic Understanding
Natural language processing to evaluate readability, jargon, sentence complexity, and content structure.
Example: Sentences over 25 words, paragraphs over 150 words, technical jargon without explanations (WCAG 3.1.5 AAA)
The Blyxo Approach
Our AI-driven browser automation combines the best of both worlds: the speed and accuracy of automated static analysis PLUS intelligent browser testing that simulates real user interactions, evaluates visual rendering, and tests dynamic behavior—catching many critical issues that static tools cannot detect.
Static Tools vs. AI-Driven Browser Testing
See exactly what accessibility issues each approach can detect.
Why This Matters
Legal Risk: The 43% of issues that static tools miss often include the most critical user-facing problems—like keyboard traps, missing focus indicators, and unannounced dynamic content.
User Impact: These missed issues directly affect users with disabilities, creating barriers that prevent them from completing tasks or accessing content.
Compliance Requirements: WCAG conformance requires testing with assistive technologies and real user scenarios—something only browser-based testing can simulate.
Business Value: Catching all issues upfront prevents costly remediation, legal challenges, and damage to your brand reputation.
Our Recommendation
The Complete Accessibility Testing Approach
AI-Driven Testing + Human Validation = True Accessibility
While our AI-driven browser automation catches many critical issues that static tools miss, we strongly recommend complementing automated testing with real device testing and validation by people with disabilities. This combination provides the most comprehensive accessibility assurance.
What Automation Provides
- Rapid identification of technical violations
- Consistent, repeatable testing across pages
- Early detection during development
- Coverage of visual and interactive issues
- Continuous monitoring and regression testing
Why Human Testing Matters
- Real-world usage with assistive technologies
- User experience and usability validation
- Context-dependent accessibility issues
- Screen reader navigation and announcements
- Cognitive and learning disability perspectives
Blyxo accelerates your testing by catching technical issues automatically, freeing up your human testers to focus on user experience, real-world workflows, and assistive technology compatibility—where human judgment is irreplaceable.
