METHOD AND SYSTEM FOR INTEGRATING TEST COVERAGE MEASUREMENTS WITH MODEL BASED TEST GENERATION

A test coverage tool provides output that identifies differences between the actual coverage provided by a test suite run on a program under test and the coverage criteria (e.g., the coverage criteria required by the test/development team management). The output from the test coverage tool is generated in the same language that was used to write the coverage criteria that are input to an automated test generator to create the test cases which form the test suite. As a result, the output from the coverage tool can be input back into the automated test generator to cause the generator to revise the test cases to correct the inadequacies. This allows iterative refinement of the test suite automatically, enabling automated test generation to be more effectively and efficiently used with more complex software and more complex test generation inputs.In preferred embodiments, test coverage analysis results of several different test suites, some manually generated and others automatically generated, are used to produce a streamlined automatically-generated test suite and/or to add missing elements to an automatically generated test-suite.
