Abstract

A method is described comprising: providing a user interface for entering data and triggering one or more operations to process the data; translating the data and/or operations to a business layer format; receiving results of the data and/or operations in a business layer format; and storing the entered data, operations and/or results in the business layer format within a test script, the test script usable to test an instance of an application at the business layer of the application.

Also described is a method for testing an application comprising: transmitting a series of business layer data and associated operations to an instance of a business layer of an application, the application processing the test data and associated operations; receiving business layer results of the associated operations; and comparing the business layer results to recorded business layer results to ensure that the application is functioning properly.
