Abstract

The present disclosure provides a system, method and computer program product that uses abstraction to enable the definition, development and maintenance of testing libraries for both simple and complex user interface controls. The system and method hide the granular details from the test designer while still promoting reuse. Using the system and method, designers can define a library of functionality for common controls that map 1-to-1 with visual controls, which may be re-implemented across many APIs or programming languages.
