In this paper, we present a replication of one of these studies, now with a larger and more representative selection of techniques and considering test suites from industrial applications as experimental objects. In addition, and although we used the same naming conventions as those used in medicine to categorize the aggregation techniques e. In other words, a decision is made on how the experiment will actually be arranged. They are driven by the desire of investigating the realm of possibilities pertaining to the functioning of a technical artefact and its interaction with the environment in the absence of a proper theory or theoretical background. Generally, the more it is replicated, the more accurate the results of the experiment will be. There are several studies concerning how understandability and modifiability are affected by refactoring in terms of several artifact-based measures. Responsibility: by Natalia Juristo, Ana M.

Natural language is often used to write software requirements specifications as well as user requirements. Moreover, the environment where they are carried out is generally academic. Analysis of One-Factor Designs with Two Alternatives. Although these changes have modified a small percentage of the vocabulary words, people are struggling to adapt to some of the new orthographic rules. On the other hand, we did not observe any statistically significant difference in the first experiment. There is no limit on the number of alternatives for using this sort of analysis.

Therefore, one of the steps taken in earlier chapters during the analysis process was to validate the mathematical model that explained the observations gathered from the experiment. Following this mission, this book is a compilation of challenges and needs of the industry, as well as research findings and achievements that could address the posed problems in software engineering. The results showed that in the context studied, the approach Agile Estimation Using Functional Metrics was best suited up. We made every effort to account for the heterogeneity of our experiments when aggregating the results obtained from them. Background: Noise, defined as an unwanted sound, is one of the commonest factors that could affect people's performance in their daily work activities. This chapter discusses in more detail this question.

We will see that this process is composed of the phases of goal definition, design, execution and analysis. However, experimental design and analysis call for special attention. Of course, you'll need to find the balance between writing code vs. If your basic functionality testing detects something that doesn't work, that's fine. This research tries to answer three questions: a Which technique is the easiest to learn in order to specify acceptance test scenarios? It demonstrates to software engineers how Experimental Design and Analysis can be used to validate their beliefs and ideas. Furthermore, research is sometimes critically reviewed for characteristics inherent to the methods.

Mobile learning m-learning applications can provide several benefits to learners. Results: Narrative synthesis and Aggregation of p-values do not take advantage of all the information contained within the raw-data for providing joint conclusions. In this paper, we describe our experience with the design of an augmented reality dressing room in which 3D models of a dress are overlaid with a color image from a camera to provide the function of a sort of virtual mirror. Our objective is to find out whether the results remain while increasing the validity in comparison to the original study. The obtained results are not trivial and show that business process obtained by means of reverse engineering has recurrent quality flaws, and the understandability and modifiability of business process models cannot be assessed by using artifact-based measures only. You don't have to try out all the different combinations of clicks and characters, or edge conditions, because that's what your testers doโ€”and they're really good at that. If you are a practitioner, the advice in this book will enable you to read and assess the studies you find in your journals and at your conferences.

Just as every field has its myths, so does the field of Software Testing. Method: We conducted a quantitative longitudinal cohort study with 30 third-year undergraduate students in Computer Science at the University of Bari in Italy. Context: Researchers from different groups and institutions are collaborating towards the construction of groups of interrelated replications. Thorough testing during the development process generally requires interactions with the end users, business clients, partners, vendors, and anyone else who may encounter or use the software being developed. Learn the differences between Software Quality Assurance and Software Quality Control. This Research to Practice Full Paper presents an empirical investigation of a pedagogical pattern language for mobile learning apps.

Some of these challenges included in the book are: increasing levels of abstraction for programming constructs, increasing levels of software reuse, increasing levels of automation, optimizing software development cycles. However, there is little evidence regarding how refactoring affects quality in terms of human-perceived measures. Basics of Software Engineering Experimentation is practically oriented and is specially written for software engineers, all the examples being based on real and fictitious software engineering experiments. As specified in Chapter 5, there is an experimental design for dealing with variables whose effect on the response variable we are not interested in. The paper also offers some considerations and intends to motivate a future discussion on this topic. The fact is this: Modern software engineers and developers engineer, design, create, and develop programs that complete hundreds of thousands โ€” if not millions โ€” of calculations per second.

We want to make your decision easier. The goal here is this: don't let other people touch your work if it's going to crash as soon as they enter their own name into the username field. However, resources tend to be limited, which places constraints on the number of replications. We have studied the role of variance in mature experimental disciplines such as medicine. Useful for all software programmers, the purpose of Software Engineering is to provide a framework to build best quality software.

All these phases are essential for the success of the experiment. Therefore, although the participants had more material to read and browse, this additional effort was paid back in the form of an improved comprehension of source code. The overall result indicates that AspectJ has a different effect on two sub-characteristics of the evolvability: understandability and changeability. The article presents the results of an experiment we conducted with database professionals in order to evaluate an approach to automatic design of the initial conceptual database model based on collaborative business process models. Technologies that make developers obtain similar performance i.
