UX is more than just about users and usability, just like testing is more than just about reporting and evaluating bugs. Behind each of these fields there is a range of check-ins that contribute to the creation of a product that caters to the need of the end user (either an individual user or a business company) in the most satisfactory manner possible. However, between these two fields of activity – UX and testing – an interdependence relationship had been established, up to the point that there are certain issues regarding the blurring of the line between the terms related to each field, which might hinder the communication between the specialist and the product itself. Therefore, there are some questions to be asked: What makes these two fields of activity rely on each other? Why are specialists required to learn and work with the terms used by both fields (e.g. as a testing specialist one also needs to be familiar with UX)? Why, before everything else, UX and testing specialists have to perceive themselves as users of the end product?
