Computer science courses, including those at the introductory level, require students to be capable of demonstrating that the programs they write satisfy the problem specifications. This demonstration of correctness is nearly always done via testing. Yet these courses tend to offer little or no guidance to the students in selecting appropriate test data. This paper analyzes the characteristics of...
Students that first learn multiple-viewed requirements modeling with UML diagrams tend to create incomplete and inconsistent models. Complex requirements and numerous modeling elements in UML often overwhelm students and make it hard for them to even notice such flaws in the models. Useful feedback can help students revise their UML models to be more complete. In this paper, we introduce a novel approach...
In software technology today, several development methodologies such as extreme programming and open source development increasingly use feedback from customer testing. This makes the customer defect data become more readily available. This paper proposes an effective use of reliability models and defect data to help managers make software release decisions by applying a strategy for selecting a suitable...
Many quality improvement activities can be guided by defect analysis. Development defect analysis of software components can be used to guide testing with the goal of focusing on parts of the software that were fault-prone during development. We perform a case study using defect data from a large software product (medical record system). In this study, development defect data help to identify which...
