Pros and Cons of Automated Accessibility Testing

📚 Quick Study Guide

🔍 Automated accessibility testing uses software to scan websites or applications for accessibility issues. ⚙️ It can quickly identify common issues like missing alt text, low contrast, and incorrect heading structures. ⏱️ Automation is fast and can be integrated into the development pipeline, but it's not a replacement for manual testing. 🚫 Automated tests can't detect all accessibility issues, especially those requiring human judgment. ➕ Pros: Speed, cost-effectiveness, early detection of issues. ➖ Cons: Limited scope, potential for false positives/negatives, inability to assess user experience. ⚖️ Balancing automated and manual testing is crucial for comprehensive accessibility. 💡 Remember WCAG (Web Content Accessibility Guidelines) are the gold standard.
