Cross-browser testing is type of testing meant to verify whether a web site or web application works correctly on the most popular real browsers, mobile devices, tablets, differently sized screens.

Cross-browser testing is a critical part of each software development process. Indeed, visual appearance of a website and its design, namely how it is displayed on a particular device, matter much to the customer.

Characteristics of cross-browser testing

Cross-browser testing of website starts with choosing a web browser. The client himself determines what web browsers the web-based application will be working in. But the goal of the program’s developer and a software tester is to let the Client know which is the main browser, learn the statistics on work of such applications in the web browsers, find out what browsers are used by the target audience.

As a rule, the testers deal with the most popular web browsers such as Google Chrome, Mozilla Firefox, Internet Explorer, Opera.

There are the main aspects to test: page proofs (color, character fonts, position of graphic images and dynamic elements) and JavaScript.

It is worth mentioning that cross browser testing needs to be conducted when the system is stable and all the functionality is debugged, otherwise different errors will be occurring and these will not be cross browser errors. And, this may involve extra financial expenses.
