The mobile app market is rapidly evolving. Currently, applications encompass all types, from various calculators to mobile games and banking apps. However, mobile app testing is a rather complex process that involves many individual features. Therefore, it is challenging to single out just a few tools for mobile testing because each specific app or team may require its own program. To address this, the mobile testing system market was studied and analyzed, identifying the most effective tools based on various indicators. The most interesting tools, in our opinion, have been collected in a series of articles (links to the first and second parts).
