Test your application
During development, transferring a web app onto a phone each time you make code changes isn’t a practical way of previewing and testing your web app. To simplify testing of a web app, Web Developer Environment integrates with the Web App Simulator(WAS) to enable testing on your computer.
You have two options for running your web app in WAS:
- Server (cloud)-based preview provides a simulation very close to the phone experience
- Local preview useful when you are working offline or want to debug your web app
