Front-end testing is a form of black box software testing in that it requires no behind-the-scenes understanding of how a software application works. It’s solely concerned with evaluating the user experience of an app. A front-end test is only effective if it tests both the functionality and visual appearance of an app, where “appearance” includes things like the layout of a page and the size, shape, color, and legibility of visual elements like buttons, form fields, and text.

What device should be used to run the tests? What operating system version, manufacturer and model to use? How to get these devices? These are some of the questions we ask ourselves when planning a mobile application testing strategy. If we consider automating these tests, other questions will surely come to mind.
