Abstract: A computer-implemented software modification method and system are disclosed. The method comprises accessing, from a data repository, definition data defining an aspect of a computer software system, the definition data being used during execution of the computer software system, the aspect comprising one or more of functionality and visual appearance of the computer software system, automatically generating a user interface in dependence on the definition data, executing the user interface and receiving, from a user, modification instructions for the aspect of the computer software system, and generating, from the modification instructions, changes to the computer software system.

Abstract: A functional behaviour test system for a target computer program includes data defining user interface functionality encoded in a data repository. The test functional behaviour system includes a definition system arranged to receive, for the target computer program, a selection of a functional behaviour test definition, the definition system further being arranged to receive an input on one or more parameters for the selected behaviour test definition to define a functional behaviour test for the target computer program, a validation system arranged to validate the functional behaviour test in dependence on the data defining user interface functionality, a data repository to store the validated functional behaviour test, and a test interface system to provide access by a substantially automated execution environment to the validated functional behaviour test in the data repository for testing of the validated functional behaviour test against the target computer program.
