Abstract: A test routine is generated for testing services to be provided over a mobile telecommunications network. Items of profile data, in the form of answers to questions such as Boolean values and such like, for a mobile device are retrieved from a database 1 (step S1). The PC 3 reads a first item of profile data (step S2) and, from the type of profile data item and, if necessary, the value of the profile data item, the PC 3 determines first whether or not a query needs to be generated (step S3). If a query needs to be generated, the PC 3 retrieves the query template corresponding to the read profile data item (step S4). From the item of profile data and the query template, the PC 3 then generates a query (step S5), e.g. a line of Xpath™ code. Once the query or queries, required for the profile data item in question has/have been generated, the PC 3 determines whether or not there are any further new profile data items for the device, e.g.
