Today, there are many browsers from different companies and each of them is capable of displaying web pages. Everyone decides which one to choose. Some people like the interface and many add-ons in Chrome, some like the simplicity of Firefox, and for some who have a small need are enough standard Edge or Internet Explorer. Which browsers are better to choose to test your site? Let's consider this issue in detail.
Ideally, you should ask the customer for a list of required browsers and devices. If that is possible, it is great. After receiving the list, we open it, arm ourselves with everything that is written in it, and then start testing :)
As practice shows, such a perfect option does not always work out and it's either the deadline is «yesterday» and there is no opportunity to write clarifying letters, or the customer does not know what he wants. The choice remains after the QA engineer. In this case, we work according to the customer-oriented logic and it may not be as easy as it seems, at first glance.
