Mobile-first is a paradigm shift in developing software where products are created with an emphasis on mobile experiences, rather than desktop. Mobile sites, native apps become the new centerfold for the company around which various other initiatives and goals are driven. This paradigm has been in adoption by major industry players including Google, facebook, Airbnb, ebay, shopify etc.

From a development standpoint it is not really different from traditional websites after you get UX but testing is quite different. You have to consider various devices, screen sizes, performance and visual testing. Automation should focus on tackling the most time consuming manual aspects which include functionality, visual parity and device compatibility.

Our $5B company has been in a mobile-first transformation this year, spanning many legacy products and teams. As a senior SDET leading the testing efforts I have been involved in various phases of this transformation. I believe this talk would give practical insights in mobile web development and testing.
