1. A computer-executed method for automatically generating addressing queries for objects rendered on a graphical user interface (GUI), wherein the method comprises: receiving a request to generate an object-addressing query for a target GUI object in an application under test; identifying an application context for the application under test; retrieving a rule document describing GUI object-addressing query rules based at least on the identified application context; parsing the rule document to obtain an applicable query rule set for the application; generating a set of query candidates for the target GUI object based at least on the applicable rule set; and determining a unique object-addressing query for the target GUI object.
