Assessing, Comparing, and Combining Statechart- based testing and Structural testing: An Experiment

Although models have been proven to be helpful in a number of software engineering activities there is still significant resistance to model-driven development. This paper investigates one specific aspect of this larger problem. It addresses the impact of using statecharts for testing class clusters that exhibit a state-dependent behavior. More precisely, it reports on a controlled experiment that investigates their impact on testing fault-detection effectiveness. Code-based, structural testing is compared to statechart-based testing and their combination is investigated to determine whether they are complementary. Results show that there is no significant difference between the fault detection effectiveness of the two test strategies but that they are significantly more effective when combined. This implies that a cost-effective strategy would specify statechart-based test cases early on, execute them once the source code is available, and then complete them with test cases based on code coverage analysis

Assessing, comparing, and combining state machine-based testing and structural testing: A series of experiments

A large number of research works have addressed the importance of models in software engineering. However, the adoption of model-based techniques in software organizations is limited since these models are perceived to be expensive and not necessarily cost-effective. Focusing on model-based testing, this paper reports on a series of controlled experiments. It investigates the impact of state machine testing on fault detection in class clusters and its cost when compared with structural testing. Based on previous work showing this is a good compromise in terms of cost and effectiveness, thi
