Abstract: A method and a device for automatically detecting potential failures in mobile applications implemented on an operating system for mobile devices, a mobile application being executable on the operating system installed on a hosting device by executing code instructions stored in an associated executable file. Provided an executable file associated to a mobile application, the device implements a module for decompiling the executable file to obtain at least one descriptive file of the mobile application containing descriptive code formatted with a markup language, a module for providing a plurality of predetermined string patterns related to potential failures, and a module for searching for the presence of at least one of the string patterns in the at least one descriptive file, and in case of presence, outputting an indication of presence of a potential failure associated to the detected string pattern.
