Nodding to the growing Progressive Web Apps (PWA) movement, Perfecto announced it's providing cloud-based automated testing of PWAs, which blend attributes of the Web and mobile.

Originated and chiefly championed by Google, PWAs use multiple technologies to blur the line between mobile apps and mobile Web sites, providing a hybrid solution that leverages benefits of each approach. Google called PWAs the future of the mobile Web and their growing popularity prompted a Gartner analyst to say, "Application leaders responsible for mobile app strategies must determine when -- not if -- they need to factor in PWAs as part of their overall mobile development strategy."
