Modeling and Re-Employment of Differential Unit Test Cases From System Test Cases
In this paper, developing effective suites of unit test cases presents a number of challenges. Specifications of unit behavior are usually informal and are often incomplete or ambiguous, leading to the development of overly general or incorrect unit tests. This paper will investigate strategies for amplifying the power and applicability of testing resources. The strategies will transform existing tests into new tests that add complementary testing capabilities to the validation process. The developed strategies will be unique in their treatment of tests as data. This will require the development of test representations that can be efficiently manipulated, and test transformations to realize operations that generate new and valuable tests.
