Introduction

Progressive Web Applications, or PWAs, are the talk of the tech world. The rise greatly aided its popularity in mobile users and the app-like experience it offers. However, what exactly is a PWA, and how does it vary from native mobile apps? What are the significant considerations a tester should bear in mind when testing PWAs, and how are they developed? Let's look at it...
Before diving right into how to test one, we should first grasp what a Progressive Web App is and what critical considerations a tester should make.
PWA is a web app that utilizes modern website capabilities to give users an app-like experience. In simple terms, it is a hybrid of a website and a mobile app.
It opens as a regular webpage in a browser and asks the user if they want to "Add to Home Screen" as they visit the website. PWA is put on the user's home screen if they approve of this prompt. It can conceal the browser UI controls and appear as an app once launched from the home screen.

Some popular PWAs are-
- Twitter lite
- Flipkart lite
- Trivago hotel booking PWA
- Forbes
- Starbucks coffee PWA etc
Features of Progressive Web Apps-
-
Responsiveness and browser compatibility- These apps are build on Progressive enhancement principles. With progressive web design, the most advanced page versions are delivered to visitors whose newer browsers can handle them while maintaining fundamental functionality and content for everyone regardless of browsers and connection quality. PWA is therefore compatible with all browsers, screen sizes, and other device requirements.
-
Offline Support- PWA supports both offline and low-quality network.
-
Push Notifications- Push notifications to play an essential role in customer engagement if used wisely.
-
Regular Updates- PWA can also self-update, like any other app.
-
An APP-like interface- These apps copy interactions and navigations of native apps.
- Discoverability- These apps are shared using URLs so they can be found easily. A user can visit on the site and include that to the home screen.
