A UML-based methodology for software component testing

This paper introduces a new UML-based SCT methodology, model-based software component testing (MBSCT), which is developed with a set of useful SCT techniques. Following the proposed iterative SCT process, developing component test cases with UML has two main phases: the first phase builds a set of UML-based test models, which is supported with the scenario-based component integration testing and test by contract techniques. The second phase designs and generates component test cases from the constructed test models, which is supported with a component test mapping technique. To demonstrate the effectiveness of the MBSCT methodology, we conduct component integration testing for a case study of a typical component-based system.
