Accessibility testing ensures that digital products like websites and apps are usable by people with disabilities. It checks compatibility with assistive technologies like screen readers, keyboard navigation, color contrast, and more, ensuring inclusive access for all users.

Cloud testing uses on-demand cloud resources over the internet to test software. It includes "testing in the cloud" for performance and compatibility checks, and "testing of the cloud" to validate the platform's own scalability and security. This approach enables massive parallel testing on real devices, reduces costs by eliminating physical labs, and accelerates release cycles. It is a fundamental practice for modern DevOps and CI/CD pipelines, despite challenges like data security. #a1qa
