As the world is growing fast in electronics, digital and mobile technologies, smartphone users are also increasing day by day and so the usage of internet data. Recent developments in new technologies are helping users to get familiar with smartphones and are helping them to find easy ways for surfing.
The term “progressive web applications” is introduced recently and it has a positive impact on mobile app development technologies. “Combining the very best qualities of the web with native apps” are termed as Progressive Web Apps.
The best part/features about native applications are push notifications and work offline feature. When compared to native apps, mobile web applications did not have the same features. Conversely, credits to web apps now all are possible. It is comprised of new Web APIs and updated web technology.
To get a clear idea about PWA we define it as- PWA (or a Progressive Web Application) is an app within your browser, displayed as a website. It does not require any downloading or installation from App Store or Google Play.
Simply, it can be defined as a website that feels like a native mobile app.
Progressive web apps will give the experience of native apps on mobile web browsers such as Chrome and Opera.
PWAs are hosted on user’s servers and can be updated without any need of issuing new updates to a play store or app store. The features of these web apps like offline working, background refresh, quick loading, push notifications, and install ability include all the capabilities like a native app offers.
The Simple structure of Progressive Web Application consists of the app shell and the dynamic/changing content.
App Shell = Static part
Content = Dynamic part
Content is referred to as the dynamic part; it always changes and is refreshed every time a connection is established with the internet.
One more technology exists that defines a PWA as a PWA. This technology is referred to as a Service Worker.
Also, a simple JSON file acts as an important part and is referred to as an app manifest. It helps the device to recognize the PWA and defines how it will be displayed on the screen.
The basic difference between a PWA and a responsive/native app is that it does not require downloading and installation like a native app from any store but it supports all features of a native app.
There are two main points that would be helpful in making a PWA:
The growth of PWA is having a sound impact on various organizations and their online growth.
We have gone through some of the principal testing techniques that are required for progressive web apps so that they closely agree to the standards and specifications.
As already seen, most of the part of PWA testing workflow depends on manual cross-browser testing. With the help of some best available tools, the burden of testing these apps manually can be significantly reduced.
Progressive web apps have enabled a new path for users to interact with websites and has allowed online businesses to involve and gain more customers. Testing of PWA is as important as building it, and time has come to take most of the advantage of this opportunity and welcome the PWA.
