I have made the web platform for cab booking service. And I want to ensure the user interface and functionality of my web application across different browsers. But there are many browsers available in the market, can you people suggest me to choose the browsers for testing?
You can search around for browser statistics over the Internet. As an example here is the stats provided by w3schools.com based on over 45 million monthly visits.
NB! The table captions are clickable so that you can drill into the details of particular browser version stats.
You would know in which region your app will be providing services or targeting customers. You can use this http://gs.statcounter.com/ to find list of browser share as per region.
We also use this in our software testing company. As per stats worldwide usage of web browsers for August 2017 Chrome : 54.89% Safari : 14.88% UC Browser : 7.43% Firefox : 5.9% Opera : 4% IE : 3.69%
Note: You should also check for mobile browsers also if you have a mobile app also.
