Testing-based process for component substitutability

Software components have emerged to ease the assembly of software systems. However, updates of systems by substitution or upgrades of components demand careful management due to stability risks of deployed systems. Replacement components must be properly evaluated to identify if they provide the expected behaviour affected by substitution. To address this problem, this paper proposes a substitutability assessment process in which the regular compatibility analysis is complemented with the use of black-box testing criteria. The purpose is to observe the components' behaviour by analysing their internal functions of data transformation, which fulfils the observability testing metric. The approach is conceptually based on the technique Back-to-Back testing. When a component should be replaced, a specific Test Suite TS is built in order to represent its behavioural facets, viz. a Component Behaviour TS. This TS is later exercised on candidate upgrades or replacement components with the purpose of identifying the required compatibility. Automation of the process is supported through the testooj tool, which constrains the conditions and steps of the whole process in order to provide a rigorous and reliable approach.Fil: Flores, Andrés Pablo.

A Software Tool for Selection and Integrability on Service Oriented Applications

Connecting services to rapidly developing service-oriented applications is a challenging issue. Selection of adequate services implies to face an overwhelming assessment effort, even with a reduced set of candidate services. On previous work we have presented an approach for service selection addressing the assessment of WSDL interfaces and the expected execution behavior of candidate services. In this paper we present a plugin for the Eclipse IDE to support the approach and to assist developers’ daily tasks on exploring services integrability. Particularly for behavioral compatibility we make use of two testing frameworks: JUnit and MuClipse to achieve a compliance testing strategy.Sociedad Argentina de Informática e Investigación Operativa (SADIO

Reuso orientado a servicios

El reuso de artefactos software brinda oportunidades para proveedores y clientes, tanto para acelerar el proceso de desarrollo de software como para establecer oferta de productos reusables. El paradigma de Computación Orientada a Servicios (SOC), promueve el desarrollo de aplicaciones distribuidas en ambientes heterogéneos, que son construidas ensamblando o componiendo servicios reusables, que se publican a través de una red y se acceden mediante protocolos específicos. SOC ha sido ampliamente adoptado bajo su implementación con la tecnología de Servicios Web, que provee flexibilidad de ejecución remota que oculta las plataformas específicas de ejecución y permite descentralizar los procesos de negocios. SOC requiere la publicación de servicios en un registro (UDDI de acuerdo a Servicios Web), los cuales luego son identificados y evaluados para una aplicación en desarrollo. Sin embargo, aún este proceso necesita métodos exhaustivos y eficientes, tanto para identificación como para selección de servicios, en el cual se puede considerar la aplicación de técnicas de Pruebas de Software y el uso de dos conceptos actuales: Orquestación y Coreografía de servicios.Eje: Ingeniería de SoftwareRed de Universidades con Carreras en Informática (RedUNCI

Assessment scheme-based service selection for SOC-based applications

Service-Oriented Computing promotes building applications by consuming reusable services. However, facing the selection of adequate services for a specific application still is a major challenge. Even with a reduced set of candidate services, the assessment effort could be overwhelming. On previous works we have presented a novel approach to assist developers on discovery, selection and integration of services, specially focusing in the selection method, which is based on a comprehensive scheme for services’ interfaces compatibility. The scheme is also complemented by a framework based on black-box testing to verify compatibility on the expected behavior of a candidate service. This paper analyzes the selection method through a series of case studies, which are designed to show the scheme’s potential on determining the best choice of a service among a set of candidates.Presentado en el VIII Workshop Ingeniería de Software (WIS)Red de Universidades con Carreras en Informática (RedUNCI

Practical Assessment Scheme to Service Selection for SOC-­based Applications

Service ­Oriented Computing promotes building applications by consuming reusable services. However, facing the selection of adequate services for a specific application still is a major challenge. Even with a reduced set of candidate services, the assessment effort could be overwhelming. On a previous work we have presented a novel approach to assist developers on discovery, selection and integration of services. This paper presents the selection method, which is based on a comprehensive scheme for services' interfaces compatibility. The scheme allows developers to gain knowledge on likely services' interactions and their required adaptations to achieve a positive integration. The scheme is also complemented by a framework based on black­box testing to verify compatibility on the expected behavior of a candidate service. The usefulness of the selection method is highlighted through a series of case studies.Sociedad Argentina de Informática e Investigación Operativ
