Progressive Web Application studio requires a manifest file. In the file, a tester should look for the following:
It has a name or short_name property.
It has the start_url property.
A 192px and 512px sized icon must be included in the Web App Manifest’s icon property.
Set the display properties to standalone, fullscreen, and minimal UI.
Validate Service worker:
A tester should ensure that the Service Worker is registered with a fetch event handler.
The website should be entirely served over HTTPS:
Safety is a key concern in the world of PWA, and testers should always ensure that the site is served via HTTPS. You may use Lighthouse by Google Developers, Jitbit, SeoSiteCheckup, DigiCert, SSL shopper, SSL Labs, and other tools to determine whether or not your website is secured or not.
Responsive web pages:
Ensure that your online application behaves responsively across all mobile and desktop platforms. You may use the Google Mobilizer tool to test the responsiveness of your web app.
As a tester, you must ensure that your web pages are accessible offline. You can make use of Lighthouse or WireMock tools to check whether the web application is able to load offline or not.
Metadata for ‘Add to Home screen:
You must determine if the web app has metadata for ‘Add to Homescreen. Lighthouse can be used to search for metadata for ‘Add to Homescreen.
Transitions should be smooth and should not be snappy even on slow networks. This should be done manually on a slow network. A tester should check the responses. When a user clicks on any button, the page should render immediately.
Each page must have a URL:
Every page on your web app must have a URL, and all URLs must be unique. Ensure that each page is linkable by a URL and that it is distinctive enough to be shared on social media or other platforms. The URLs can also be opened in new browsers directly.
A tester should test push notifications while keeping in mind that they are not too aggressive. They should also seek permission from the user.
