Abstract

A computer operable method for integrating and automating test procedures within a computer application program. Instantiated test operation objects of an object class defined by the present invention correspond to functions to be tested within the computer application program. The test operation objects are instantiated by calls to functions in a test operation runtime library (DLL). The test operation objects include interface method functions which execute the intended test operation and simulate any required data, file, or memory I/O. Other aspects of the methods of the present invention provide rules which permit decisions as to the applicability of each test operation given the state of the application program or the context of the test operation sequence. The various test operation objects are selected to perform a sequence of test steps. In one mode of operation, the methods of the present invention randomly select among all the instantiated test operation objects. In another mode of operation, the methods of the present invention “playback” a previously recorded sequence of test operation objects to permit reproduction of failures in previous test sequences. In a third mode of operation, the methods of the present invention permit a user to modify or create “playback” files to customize a test case for a particular focus.

Claims

1. A software product having an application program including:

application program objects operational when executed by a computing environment to direct the computing environment to perform an application function;

test objects embedded within the application program and operational when executed by the computing environment to direct the computing environment to test the application program objects; and

a storage medium operational to store the application program objects and the test objects.

2. The software product of claim 1 wherein the test objects are derived from a dynamic link library invoked by the application program.

3. The software product of claim 2 wherein the test objects are operational when executed by the computing environment to direct the computing environment to randomly and automatically test the application program objects.
