White-Box Testing Framework for Object-Oriented Programming based on Message Sequence Specification

Software is a crucial element in the functionality of devices and industry. Likewise, the operation of an enterprise or organization depends largely on the reliability of the software systems used for supporting the business process or particular tasks. The quality of software has become the most important factor in determining the success of products or enterprises. In order to accomplish a quality software product several methodologies, techniques, and frameworks have been developed, each of them tailored to specific areas or characteristics of the software under review. This paper presents a white-box testing framework for Object- Oriented Programming based on Message Sequence Specification. In the context of an object-oriented program, our framework can be used to test the correct order in which the methods of a class are invoked by its clients. The implementation of the framework is based on aspect-oriented programming.XV Workshop Ingeniería de Software (WIS)Red de Universidades con Carreras en Informática (RedUNCI

A Vision for Behavioural Model-Driven Validation of Software Product Lines

International audienceThe Software Product Lines (SPLs) paradigm promises faster development cycles and increased quality by systematically reusing software assets. This paradigm considers a family of systems, each of which can be obtained by a selection of features in a variability model. Though essential, providing Quality Assurance (QA) techniques for SPLs has long been perceived as a very difficult challenge due to the combinatorics induced by variability and for which very few techniques were available. Recently, important progress has been made by the model-checking and testing communities to address this QA challenge, in a very disparate way though. We present our vision for a unified framework combining model-checking and testing approaches applied to behavioural models of SPLs. Our vision relies on Featured Transition Systems (FTSs), an extension of transition systems supporting variability. This vision is also based on model-driven technologies to support practical SPL modelling and orchestrate various QA scenarios. We illustrate such scenarios on a vending machine SPL

Model-Based Verification for SIMULINK Design

Testing a Model-Based design is the only way to determine the correctness of the designed model but not enough to conclude that the design is error free. Verification exposes all the design errors and describes the functionality of the system. Assertion based verification helps to determine whether the model obey the actual design requirements. This thesis work is mainly based on verification of a Water Tank control system modeling using SIMULINK model

Black-Box Testing Technique for Information Visualization. Sequencing Constraints with Low-Level Interactions

The software development process has matured significantly over the past decade. We are currently in a state where the need for the verification and validation of the product under development is unquestionable. Visualizations, as software products, must go through such verification and validation control. At the implementation level, a visualization software is no different from any other software, its source code can be verified and validated by using any available white-box technique. The usability studies and controlled experiments are helpful to understand how the user perceives and uses the visualization. However, at an interaction level, a visualization software is not like any other software. Most interactions on a traditional software, are based on buttons and text fields while on a visualization, the interactions are mostly based on zooming, selecting and filtering visual elements. The black-box techniques found in the literature, also known as functional tests, are not suitable for this context. This paper describes a black-box technique tailored for information visualization implementations. The technique is built on constraints imposed over the sequences of low-level interactions available in the visualization and the User Action Notation.Facultad de Informátic

Automatic model - based test case generation for uml diagrams using tree travelsal algorithm

The foundation of any model-based testing (MBT) with Unified Modelling Language (UML) diagrams is test case generation (TCG) which predicts the expected functionalities of a system under test (SUT). However, problems associated with existing test case generation methods are lack of integration with various UML diagrams and tools, inability to cover all the model elements of UML diagrams, failure to generate comprehensive test cases based on adequate coverage criteria and lack of support tools for automatic generation of test cases. To address these challenges, efficient mapping strategies for model elements that engenders effective artefacts extraction and test case generation processes were proposed. The methodology employed in this research comprised constructing relevant models and algorithms as well as implementing with the use of Java programming language. Specifically, an enhanced elements mapper, artefacts extractor (parser) and test case generator were developed and integrated to produce the support tool. The elements mapper yielded an accuracy result of 99.31%. The artefacts extractor recorded 99.64% accuracy while the test case generator recorded 100% accuracy. The improved methods proved to be more robust and efficiently generated quality test cases with eliminated redundancies based on all the descriptive attributes of UML diagrams. Limitations of existing the methods were addressed in the proposed method which is able to integrate more diagrams to generate quality test cases
