Test cases are an essential tool in software quality assurance: they ensure that code behaves as specified in the requirement. However, writing test cases does not have only benefits, it comes with a cost: the programmer has to formulate the test cases and maintain them when the tested source code changes. Particularly for start-ups or small enterprises such costs become prohibitive, which often prefer...
Key among the grand challenges in traceability are those that lead to achieving traceability as a by-product of the natural software development life cycle. This position paper profiles test-driven development (TDD), an emerging software development practice, in which automated tests and code satisfying them are developed in rapid succession over multiple iterations. Our position is that the nature...
Engineering educators struggle with ldquosoftrdquo topics - topics which include a social element. Soft engineering topics are distinct from the scientific and mathematical underpinnings of engineering. Students frequently complain when these topics are integrated into engineering curricula. Engineering educators also express concerns that they lack both preparation and ability to teach these topics.
As digital resources increasingly growing and the economic benefit of digital intellectual property rights being increasingly important, people has been increasingly emphasis on information security issues brought by the data remnants in storage devices. They try their best to prevent the potential risks. In this paper, we survey comprehensively related technologies, standards and trends of erasure,...
We describe a benchmark of publicly-available multi-threaded programs with documented bugs in them. This project was initiated a few years ago with the goal of helping research groups in the fields of concurrent testing and debugging to develop tools and algorithms that improve the quality of concurrent programs. We present a survey of usage of the benchmark, concluding that the benchmark had an impact...
Distributed software systems are characterized by increasing autonomy. They often have the capability to sense the environment and react to it, discover the presence of other systems and take advantage of their services, adapt and re-configure themselves in accordance with the internal as well as the global state. Testing this kind of systems is challenging, and systematic and automated approaches...
Model-based testing of state based systems is known to be able to spot non-conformance issues. However, up to half of these issues appear to be errors in the model rather than in the system under test. Errors in the specification at least hamper the prompt delivery of the software, so it is worth while to invest in the quality of the specification. Worse, errors in the specification that are also...
Some approaches to Model-Based Testing focus on test case generation from assertions (operation pre- and post- conditions) and invariants, e.g., written in the Object Constraint Language. In such a setting, assertions must be validated. Validation is often carried out via executing scenarios wherein system operations are applied, to detect unsatisfied invariants or failed preconditions. This paper...
Software testing plays an important role in the life cycle of software development. Because software testing is very costly and tedious, many techniques have been proposed to automate it. One technique that has achieved good results is the use of search algorithms. Because most previous work on search algorithms has been of an empirical nature, there is a need for theoretical results that confirm...
This paper provides an overview of work being done in the EntryPoint project, which is examining the first course work in computing degrees. A key goal of this project is to move away from the traditional CS1/CS2 programming courses as the start of a computing degree. In addition, the project team is looking at how these ideas might be extended to BSSE degree programs. As such, this paper will discuss...
