Adaptation of Software Testability Concept for Test Suite Generation : A systematic review

Malla, Prakash, Gurung, Bhupendra January 2012 (has links)
Context: Software testability, which is the degree to which a software artifact facilitates process of testing, is not only the indication of the test process effectiveness but also gives the new perspective on code development. Since more than fifty percent of total software development costs is related to testing process activities, Software testability has always been the improving area in software domain so that we can make the software development process effective with respect to test cases writing and fault detection process. Objectives: The research though this thesis will have the objective of proposing a conceptual framework considering the testability issues for the simpler test suite generation and facilitating the concerned persons with better effectiveness of testing. We investigate the testability factors and testability metrics basically with the help of the systematic literature review and the proposed framework’s feasibility is evaluated with case study. Methods: Initially, we conduct the literature review to get broad knowledge on this domain as well for the key documents. Then study starts with the systematic literature review process guided by the review protocol to collect the testability factors and measurements. The framework is validated with the case study. The research documents are included from highly trusted e-database including Compendex, Inspec, IEEE Xplore, ACM Digital Library, Springer Link and Scopus. Altogether 36 primary documents are included for the study and results are extracted. Results: From the results of systematic literature review, Software testability factors and associated measurements are found and the construction of framework for simple test generation as guidelines evaluate with case study. To make the test suite generation simpler, we propped a framework based on the FTA concepts and breakdown of high level testability factors to its simpler form of measureable level. Conclusions: Numbers of different software testability factors are presented in different researches in different perspectives. We collect important testability factors and associated measurement methods and we concluded the effect of testability in simpler test suite generation with the help of framework evaluated by case study.

Avaliação de atributos de testabilidade para sistemas de suporte à decisão / Testability attributes assessment for decision support systems

Geromini, Marcos Fernando 11 March 2016 (has links)
As organizações públicas e privadas são constantemente expostas a fatores internos e externos, que podem comprometer sua estabilidade diante das oscilações da economia e dos concorrentes. Nestas empresas, os tomadores de decisão são essenciais para analisar e avaliar todas as variáveis que envolvem estes fatores, com o objetivo de identificar o melhor caminho para os negócios. Entretanto, conseguir gerenciar os dados internos e externos à organização não é uma atividade simples. Neste contexto, os Sistemas de Suporte à Decisão (SSD) tornaram-se fundamentais para auxiliar os tomadores de decisão na solução de problemas mal estruturados ou sem nenhuma estruturação. Porém, a complexidade que envolve os projetos de implantação ou desenvolvimento de um SSD, geralmente compromete a efetividade dos testes que garantem a conformidade do sistema em relação às especificações previamente definidas. Uma solução para esse problema é considerar os atributos ou fatores de testabilidade nestes projetos, pois podem elevar o grau de eficácia e eficiência da atividade de teste e consequentemente contribuírem para redução do tempo e custos do projeto. Portanto, conseguir identificar esses atributos ou fatores que tenham influência na testabilidade dos SSD e algum método que permita analisar e avaliar o quanto estão presentes neste sistema, é essencial para aumentar a qualidade do sistema. Diante desta necessidade, este trabalho investigou e selecionou os principais fatores que podem influenciar no grau de testabilidade de um software e propôs um método para analisar e avaliar o quanto o SSD está considerando esses fatores em sua arquitetura. Com o objetivo de avaliar e validar o método de análise e avaliação, foram realizados testes de aplicabilidade em empresas de pequeno, médio e grande porte, bem como no meio acadêmico. Com os resultados obtidos nos testes, foi possível concluir que o método é específico para SSD, que pode ser usado como um guia durante o processo de desenvolvimento e auxiliar na classificação de SSD quanto a sua testabilidade. / Public and private organizations are constantly exposed to internal and external factors which could compromise their stability in the face of fluctuations in the economy and competitors. In these companies, decision makers are essential to analyze and evaluate all the variables regarding these factors, in order to identify the best way for business. However, managing internal and external data of the organization is not a simple activity. In this context, Decision Support Systems (DSS) have become essential to assist decision makers in solving unstructured problems or lock of structure. However, the complexity involved in the implementation of projects or development of a DSS usually compromises the effectiveness of tests that ensure compliance of the system in relation to previously defined specifications. One solution to this problem is to consider the attributes or testability factors in these projects, since they can raise the level of effectiveness and efficiency of testing activity and thus contribute to reducing the time and project costs. Therefore, the ability to identify these attributes or factors that influence testability of DSS and a process for analyzing and evaluating how much the present in this system, is essential to increase system quality. Given this need, this work investigated and selected the main factors that can influence the degree of testability of software and proposed a way to analyze and assess how the DSS is considering these factors in its architecture. In order to evaluate and validate the analysis and evaluation method, applicability tests were performed in small, medium and large companies, as well as in academy. As results obtained in the tests, it was concluded that the method is specific for DSS, which can be used as a guide during the development process and assist in the DSS classification regarding its testability.
