Test Case Development During OO Life-Cycle and Evolution

Testing is considered as integral to every phase of the OO life-cycle to ensure a well developed test suite covering requirements, design and structure. Release criteria between the phases of development incorporate test suite addition and documentation allowing traceability from requirements through coding to specific test cases. Software engineers can pool their knowledge via the test suite and this expertise can be used for regression testing after system alteration or for re-use considerations. 1 Introduction Testing is a major problem in Object Oriented (OO) Code development. Much research effort has gone into design and requirements analysis but little has been expended on the mechanics of testing for product release, regression or re-use of code. This paper addresses a method of development which encompasses testing at all phases of a system life-cycle. If testing is performed as an integral part to development, test data can be created that is traceable to particular phases ..
