While these tests reflect important insights of the developers (e.g., which parts of the software need testing and what inputs should be used), they are usually not persistent and are easily forgotten. They cannot always be re-executed automatically, for example to debug or to test for regressions. Several methods that make such...
The student project is a key component of a software engineering course. What exact goals should the project have, and how should the instructors focus it? While in most cases projects are artificially designed for the course, we use a deployable, realistic project. This paper presents the rationale for such an approach and assesses our experience with it, drawing on this experience to present guidelines...
Software development has undergone a major change in recent years, partly but not only as a result of the outsourcing phenomenon. Most software projects today are distributed, raising a whole slate of new issues of management, coordination, licensing, stakeholder involvement, specification, quality assurance (in particular testing) and maintenance. While there has been much discussion of the political...
A program, or in object-oriented programming a feature, is characterized not only by an implementation but by a contract specifying its intent and a proof obligation to ascertain that the implementation meets the contract.
