What is UX Testing?
UX testing is a research aiming to determine whether a tested interface is convenient for its intended goal. It is performed only by real people coming from the target audience. There are two UX testing approaches – qualitative and quantitative. The quantitative approach gathers statistical data on respondent behavior within a certain number of respondents.The qualitative approach reflects respondent’s impression on the product. The quantitative approach requires up to 30 persons, but it is only necessary for large-scale projects. For the qualitative approach, 3-5 persons are usually enough. In most usability testings the qualitative approach is used. A person is asked to perform a certain action/task within the given interface (for example, to make an online purchase, sign up for a newsletter, publish a post/photo, etc), while the host traces his/her behavior patterns (comments, assumptions failures, difficulties, etc.).
