What do we know about software testing in the real world? It seems we know from Fred Brooks’ seminal work “The Mythical Man-Month” that 50% of project effort is spent on testing. However, due to the enormous advances in software engineering in the past 40 years, the question stands: Is this observation still true? In fact, was it ever true? The...

The use of dynamic information to aid in software understanding is a common practice nowadays. One of the many approaches concerns the comprehension of execution traces. A major issue in this context is scalability: due to the vast amounts of information, it is a very difficult task to successfully find your way through such traces without...

In development processes with high code production rates testing typically triggers fault diagnosis to localize the detected failures. However, current test prioritization algorithms are tuned for failure detection rate rather than diagnostic information. Consequently, unnecessary diagnostic effort might be spent to localize the faults. We...

One way of gaining understanding of a software system is the analysis of dynamic information, i.e., program execution traces. A problem regarding the analysis of such traces is the fact that these are often extremely large: hundreds of thousands and even millions of calls within a single trace are no exception. To aid a user in navigating and...

In this thesis, we have focused on applying Spectrum-based Fault Localization (SFL) to diagnose Service-Oriented Systems at runtime. We reused a framework-based online monitoring technique to obtain the service transaction information. We devised a three-phased oracle and combined this with monitoring to detect system failures at runtime. Both...

In online communities, users frequently interact with strangers in order to buy and sell products, watch videos, educating themselves, and playing games. Establishing trust among strangers is essential for the functionality of these communities but challenging, as well. Online reputation systems effectively establish trust among strangers by...

The formal definition the semantics of a programming language and its implementation are typically separately defined, with the risk of divergence such that properties of the formal semantics are not properties of the implementation. In this paper, we present DynSem, a domain-specific language for the specification of the dynamic semantics of...

Recent studies have shown that the violation of the Interface Segregation Principle (ISP) is critical for maintaining and evolving software systems. Fat interfaces (i.e., interfaces violating the ISP) change more frequently and degrade the quality of the components coupled to them. According to the ISP the interfaces’ design should force no...

System administrators and developers who deploy distributed systems have to deal with a deployment process that is largely manual and hard to reproduce. This paper describes how networks of computer systems can be reproducibly and automatically deployed from declarative specifications. Reproducibility also ensures that users can easily...

Our analysis of crosscutting concerns in real-life software systems (totaling over 500,000 LOC) and in aspect-oriented literature, indicated a number of properties that allow for their decomposition in primitive building blocks which are atomic crosscutting concerns. We identify these blocks as crosscutting concern sorts, and we use them to...

In this paper, we present a descriptive case study covering the re-engineering and furhter evolution of adopting service oriented architecture (SOA) in industry. The goal of this case study is to identify the possible benefits and bottlenecks of adopting SOA, as well as to come up with best practices and research directions based on real-life...

Model-based diagnosis is an area of abductive inference that uses a system model, together with observations about system behavior, to isolate sets of faulty components (diagnoses) that explain the observed behavior, according to some minimality criterion. This thesis presents greedy approximation algorithms for three problems closely related to...

Testing plug-in-based systems is challenging due to complex interactions among many different plug-ins, and variations in version and configuration. The objective of this paper is to increase our understanding of what testers and developers think and do when it comes to testing plug-inbased systems. To that end, we conduct a qualitative ...

A medium-sized west-European telecom company experienced a worsening trend in performance, indicating that the organization did not learn from history, in combination with much time and energy spent on preparation and review of project proposals. In order to create more transparency in the supplier proposal process a pilot was started on...

The program comprehension research community has been developing useful tools and techniques to support developers in the time-consuming activity of understanding software artifacts. However, the majority of the tools do not bring collective benefit to the team: After gaining the necessary understanding of an artifact (e.g., using a technique...

We report on an industrial case study on developing the embedded software for a smart meter using the C programming language and domain-specific extensions of C such as components, physical units, state machines, registers and interrupts. We find that the extensions help significantly with managing the complexity of the software. They improve...

Software written in one language often needs to construct sentences in another language, such as SQL queries, XML output, or shell command invocations. This is almost always done using unhygienic string manipulation, the concatenation of constants and client-supplied strings. A client can then supply specially crafted input that causes the...
