How choose the order of the browsers that I will be testing ?

By testing your web application using a variety of web browser types, you better emulate the UI experience of your users who may run different browsers. For example, your application might include a control or code in Internet Explorer that is not compatible with other web browsers. By running your coded UI tests across other browsers, you can discover and correct any issue before it impacts your customers.

To discover what is the priority that you should test the browsers is simple, but you have a lot of points to worry.

– Hardware differences

– Monitor resolution settings

– Browser and computer preferences

Usage of each browser 

What is the time that you have ?

When you will be the release ?

How to measure the order of the browsers ?

The ideal is you focus in the most usage browser first and after you can think about the others. So, let’s imagine that you have 4 weeks to test all browsers and you take 1 week to test all the scenarios in one browser. You need to choose the first week to test in the most used browser for your end user, and the second week for the second most used and so on.

This is the ideal in the most of cases, but of course everything depends of how many people you have to help you with the tests, the date of the release, and the other points I already told.










– Don’t Overestimate neither Underestimate a browser version.

– If you are looking for just mainstream use, StatCounter has a really nice graph to show you what browser you should test.
