A new approach to event- and model-based feature-driven software testing and comparison with similar approaches

A software can be thought as a composition of features. Feature-oriented software development (FOSD) builds the development process on features. Part of the FOSD process is testing, and accordingly, it should be feature-driven. In model-based testing, test cases are systematically generated using the model. This research concentrates on event-based graphical models and utilizes event sequence graphs (ESGs). We develop a new test sequence generation algorithm for ESGs and named it short and frequent test sequences (SFT). Then we compare it with the existing test sequence generation algorithm called TSD. Moreover, we introduce two model-building approaches, namely daisy and swim lane, for ESGs and analyze their effects on feature-driven testing. For the evaluation, we use five different feature-driven software models. The evaluation results shows that both modeling approaches are advantageous in certain test objectives. For testing the software product as a whole, test sequence(s) should be generated by TSD from daisy modeled ESG. If a certain feature within the software product or its interaction with another feature is to be tested, then test sequence(s) should be generated by SFT from swim lane modeled ESG.

Recommended Features of Learning Management System Using Feature-Oriented Method Software Development on Moodle

Learning Management System (LMS) serves as a learning media effective for online learning during Covid-19. The rising use of LMS these days indicates that LMS features need to be further measured for their relevance to the National Standards of Higher Education (SN-Dikti). This measurement is also essential to be applied for five blended learning criteria for flexible time and place to access lessons. The objective of this research is to analyze the features of the LMS implemented on Moodle version 3.10. The analysis of the features was carried out by employing the methods of Feature-Oriented Software Development (FOSD), a method that elaborates software system relating to existing features of LMS, involving: 1) Canvas; 2) Edmodo; 3) Google Classroom; 4) Moodle; 5) Zoom Meeting; 6) Google Meet; 7) efront, and 8) Microsoft Teams. In accord with the testing and validation by experts, the research revealed that there were 56 features of LMS pertinent to learning and assessment standards of SN-Dikti and E-learning self-study criteria with other blended-media or events, instructor-led program, live e-learning, on the job training, simulation, and lab centered on blended learning. Those 56 features were approved by experts and implemented by employing Moodle version 3.10 relevant to the SN-Dikti and blended learning

Development of mobile-based health center information system with feature-oriented software development (case study in North Kuta health center)

Health center is a district/city official technical unit that responsible for handling health development. At North Kuta Health Center, the medical record has been managed using a web-based application information system. Most of the patients access this system via smartphone. However, the system interface is not optimal if accessed via smartphone, such as the buttons on the system are covered by other interface elements and image sizes exceed the smartphone screen. For this reason, a mobile-based information system was developed from the existing health center system. When developing the system, a Feature-Oriented Software Development (FOSD) method was applied. The FOSD method applied the stages of domain analysis, domain design and specifications, domain implementation, product configuration, and generation. The domain analysis stage produced a needs analysis. At the domain design and specification stage, requirements analysis was processed into system design. The system design was created into a system prototype at the domain implementation stage. At the product configuration and generation stages, the system prototype was tested with User Acceptance Test (UAT) and running time. Running time testing shows the average time needed by the prototype system to complete each process was 432 ms. The UAT test shows that the prototype system was running well under the health service business process at the North Kuta Health Center. The system prototype has also provided convenience in the operation of health services in the North Kuta Health Center.

Feature dependencies in automotive software systems: Extent, awareness, and refactoring

Many automotive companies consider their software development process to be feature-oriented. In the past, features were regarded as isolated system parts developed and tested by developers from different departments. However, in modern vehicles, features are more and more connected and their behavior depends on each other in many situations. In this article, we describe how feature-oriented software development is conducted in automotive companies and which challenges arise from that. We present an empirical analysis of feature dependencies in three real-world automotive systems. The analysis shows that features in modern vehicles are highly interdependent. Furthermore, the study reveals that developers are not aware of these dependencies in most cases. For the three examined cases, we show that less than 12% of the components in the system architecture are responsible for more than 90% of the feature dependencies. Finally, we propose a refactoring approach for implicit communal components, which makes them explicit by moving them to a dedicated platform component layer.

Extended Feature Algebra

Feature Algebra was introduced as an abstract framework for feature-oriented software development. One goal is to provide a common, clearly defined basis for the key ideas of feature-orientation. The algebra captures major aspects of feature-orientation, such as the hierarchical structure of features and feature composition. However, as we will show, it is not able to model aspects at the level of code, i.e., situations where code fragments of different features have to be merged. In other words, it does not reflect details of concrete implementations.In this paper we first present concrete models for the original axioms of Feature Algebra which represent the main concepts of feature-oriented programs. This shows that the abstract Feature Algebra can be interpreted in different ways. We then use these models to show that the axioms of Feature Algebra do not properly reflect all aspects of feature-orientation from the level of directory structures down to the level of actual code. This gives motivation to extend the abstract algebra, which is the second main contribution of the paper. We modify the axioms and introduce the concept of an Extended Feature Algebra. As third contribution, we introduce more operators to cover concepts like overriding in the abstract setting.

Exploring modal worlds

Modal idempotent semirings cover a large set of different applications. The paper presents a small collection of these, ranging from algebraic logics for program correctness over bisimulation refinement, formal concept analysis, database preferences to feature oriented software development. We provide new results and/or views on these domains; the modal semiring setting allows a concise and unified treatment, while being more general than, e.g., standard relation algebra.

New Set of Metrics for Accessing Usability in Feature Oriented Programming

Quality and complexity assessment are critical aspects in feature oriented software development. Feature oriented development is part of software product line methodology where software is framed using feature concept. In course of research; object oriented metrics are being used to assess the quality of feature model. But these metrics limit the complexity within the features and complexity across the classes and features relationship are untouched .This state of art proposes a new set of metrics to provide usability and complexity assessment crosswise the feature-class relationship. This will provide better understanding of feature oriented system and help to develop a sustainable system.

FeatureIDE: An extensible framework for feature-oriented software development

FeatureIDE is an open-source framework for feature-oriented software development (FOSD) based on Eclipse. FOSD is a paradigm for the construction, customization, and synthesis of software systems. Code artifacts are mapped to features, and a customized software system can be generated given a selection of features. The set of software systems that can be generated is called a software product line (SPL). FeatureIDE supports several FOSD implementation techniques such as feature-oriented programming, aspect-oriented programming, delta-oriented programming, and preprocessors. All phases of FOSD are supported in FeatureIDE, namely domain analysis, requirements analysis, domain implementation, and software generation.

An algebraic foundation for automatic feature-based program synthesis

Feature-Oriented Software Development provides a multitude of formalisms, methods, languages, and tools for building variable, customizable, and extensible software. Along different lines of research, different notions of a feature have been developed. Although these notions have similar goals, no common basis for evaluation, comparison, and integration exists. We present a feature algebra that captures the key ideas of feature orientation and that provides a common ground for current and future research in this field, on which also alternative options can be explored. Furthermore, our algebraic framework is meant to serve as a basis for the development of the technology of automatic feature-based program synthesis and architectural metaprogramming.
