Le test constitue aujourd'hui la principale activité de validation d'un logiciel. Dans un contexte où l'on cherche à réduire les coûts et augmenter la qualité, il est essentiel de proposer des solutions de test automatisées et de veiller à la productivité des ingénieurs de test. Les travaux présentés dans ce mémoire ont l'ambition de contribuer à ces objectifs. Ces travaux se déclinent selon trois axes. Le premier axe concerne la génération de tests. L'originalité du travail se situe dans l'établissement de principes pour la production combinatoire de suites de test, à partir d'expressions abstraites. Ces principes ont été implantés dans un outil appelé Tobias. Lorsque de grandes suites de test sont produites, il est important d'automatiser l'oracle des tests. Un deuxième axe vise à évaluer l'utililisabilité des assertions pour établir le verdict des tests pour des applications domotiques. Les résultats montrent que les assertions sont effectivement utilisables, mais que l'exécution de ces applications dans un environnement réel non complètement contrôlable ou observable peut conduire en l'émission de verdicts biaisés. Ainsi, l'automatisation de la génération et de l'oracle permet de réduire le coût de la phase de test. Mais, pour réduire le coût du test, il est aussi important de considérer les facteurs internes au logiciel relatifs à la testabilité. De nombreuses métriques ont été proposées pour prédire et estimer la testabilité d'un système. Un troisième axe de recherche concerne l'évaluation la validation expérimentale de ces métriques. Les résultats des expérimentations démontrent que les métriques étudiées ne sont pas directement utilisables pour prédire le coût du test.

In this thesis, implementations of Enterprise Resource Planning Systems are studied with a broader view. Pre-implementation preparations and post-implementation developments play key roles in the success of the ERP utilization of the companies. To find out how the success can be achieved, various concepts in ERP implementation are analyzed. Using analogies with the basic software development models, common application methodologies are studied. The study is completed with the analysis of an interesting and challenging ERP implementation experience, focusing on the important decision points.

abstract: The human motion is defined as an amalgamation of several physical traits such as bipedal locomotion, posture and manual dexterity, and mental expectation. In addition to the “positive” body form defined by these traits, casting light on the body produces a “negative” of the body: its shadow. We often interchangeably use with silhouettes in the place of shadow to emphasize indifference to interior features. In a manner of speaking, the shadow is an alter ego that imitates the individual. The principal value of shadow is its non-invasive behaviour of reflecting precisely the actions of the individual it is attached to. Nonetheless we can still think of the body’s shadow not as the body but its alter ego. Based on this premise, my thesis creates an experiential system that extracts the data related to the contour of your human shape and gives it a texture and life of its own, so as to emulate your movements and postures, and to be your extension. In technical terms, my thesis extracts abstraction from a pre-indexed database that could be generated from an offline data set or in real time to complement these actions of a user in front of a low-cost optical motion capture device like the Microsoft Kinect. This notion could be the system’s interpretation of the action which creates modularized art through the abstraction’s ‘similarity’ to the live action. Through my research, I have developed a stable system that tackles various connotations associated with shadows and the need to determine the ideal features that contribute to the relevance of the actions performed. The implication of Factor Oracle [3] pattern interpretation is tested with a feature bin of videos. The system also is flexible towards several methods of Nearest Neighbours searches and a machine learning module to derive the same output. The overall purpose is to establish this in real time and provide a constant feedback to the user. This can be expanded to handle larger dynamic data. In addition to estimating human actions, my thesis best tries to test various Nearest Neighbour search methods in real time depending upon the data stream. This provides a basis to understand varying parameters that complement human activity recognition and feature matching in real time. / Dissertation/Thesis / Masters Thesis Electrical Engineering 2016

Syftet med arbetet som beskrivs i denna rapport var att undersöka om den Oracle-baserade laborationsmiljö som användes hos ADIT gick att överföra till MySQL. Oracle är ett komplext system som är krävande att administrera, något som ADIT ansvarat för med egen personal och egen hårdvara och detta var inte idealiskt. I kombination med ett stort intresse från studenter att använda just MySQL vid laborationer hos ADIT beslutades det att man skulle undersöka om MySQL nu var moget att axla den roll som Oracle tidigare haft. Utifrån detta går rapporten igenom vad som behövde göras med det befintliga laborationsmaterialet. En introduktion till relations¬modellen och SQL samt förklaringar av skillnader i features mellan Oracle och MySQL som hade betydelse för laborationerna återfinns också. Det visade sig att överföringen var enkel att göra och sist i rapporten sammanställs våra erfarenheter.

Existem poucos trabalhos enfocando o teste de regras e os que o fazem não exploram a linguagem SQL, uma das linguagens mais utilizadas em bancos de dados relacionais. Propõe-se neste trabalho uma ferramenta de suporte ao teste de unidade de regras ativas ¿ a ferramenta ART-TOOL (Active Rule Testing Tool). Técnicas de teste estrutural de software foram adaptadas para apoiar a aplicação de critérios baseados em análise de fluxo de dados ao teste de regras ativas. O suporte da ART-TOOL dá-se por meio de análises estática e dinâmica de regras ativas envolvendo: determinação dos elementos requeridos pelos critérios; a instrumentação do código fonte da regra; a monitoração da execução da regra instrumentada; e a análise de cobertura dos critérios. Um exemplo mostra a aplicação da ferramenta no teste de uma regra ativa. Mostra-se também, no teste de 15 regras ativas, que a abordagem contribui para a revelação de defeitos / Abstract: Active rules define actions on active databases, activated without the intervention of the user; they are used for the maintenance of a database as well as for controlling diverse other activities. There is few work focusing on the test of rules and the existing ones do not explore the SQL language, one of the most used languages in relational databases. A tool is proposed to support the unit test of active rules - the ART-TOOL (Active Rule Testing Tool). Structural software testing techniques are adapted to support the application of criteria based on data flow analysis to the test of active rules. ARTTOOL provides testing support by means of static and dynamic analyses of active rules involving: determination of the required elements for the criteria; instrumentation of the source code of the rule; execution of the instrumented rule; and coverage analysis of the criteria. An example shows the application of the tool in the test of an active rule. It is also shown, through the test of 15 active rules, that the approach contributes to revealing faults in rules / Mestrado / Engenharia de Computação / Mestre em Engenharia Elétrica

I dagens hårda konkurrenssituation krävs det mer och mer av företags informations-system. Detta gör att fler och fler företag väljer att implementera ett integrerat affärs-system. Integreringen gör att företag får en enhetlig systemmiljö för hela företagets informationsbehandling. Implementeringen är dock en kostsam och tidskrävande process (Ekstrand, 1998). Mitt arbete behandlar frågeställningarna om varför företag väljer att implementera ett affärssystem, hur implementeringen förlöpte samt hur affärssystemet fungerar när implementeringen är färdig. Bland de företag jag vände mig till så var den främsta anledningen till att företag installerar ett affärssystem att systemen är omfattande och integrerade. Jag kom även till slutsatsen att det nästan är omöjligt att genomföra en implementering av ett affärssystem helt smärtfritt. Problemen beror dock inte alltid på affärssystemet utan på t.ex. dålig beredskap från företagens sida. Sammanfattningsvis fick jag intrycket att de flesta företag är nöjda med sitt val av system och de som inte ännu såg nyttan med systemen trodde att de inom kort skulle göra det.

[pt] A rastreabilidade de requisitos eficaz oferece suporte para alcançar maior maturidade do projeto e melhor qualidade do produto. Pesquisadores argumentam que a rastreabilidade deve ser explicitamente definida antecipadamente e que a rastreabilidade eficaz acontece por acaso ou por meio de esforços ad-hoc. Além disso, estudos comprovam que os profissionais raramente seguem estratégias de rastreabilidade explícitas. Tal estratégia explícita de rastreabilidade deve, pelo menos, definir os artefatos a serem rastreados e os traços a serem criados entre eles. Considerando o ambiente de desenvolvimento de procedures Oracle, raramente se percebe alguma estratégia de rastreabilidade, especialmente entre a especificação de requisitos e o código SQL, o que torna a manutenção das procedures Oracle muito dispendiosa. Este trabalho apresenta como proposta, um processo que facilita a definição explícita de estratégias de rastreabilidade e que contém atividades necessárias para a elaboração de metas de uso da rastreabilidade. O processo também inclui atividades de projeto de rastreabilidade e validação de estratégia. Como estudo de caso, é realizada a instanciação do processo em um ambiente de desenvolvimento Oracle, onde se faz uso de modelos de rastreabilidade. / [en] Effective requirements traceability supports higher project maturity and better product quality. Researchers argue that traceability must be explicitly defined in advance and to be effective. In addition, studies show that professionals rarely follow explicit traceability strategies. An explicit traceability strategy should at least define the artifacts to be traced and the traits being created between them. Usually in a development environment of Oracle procedures, a traceability strategy is rare, especially between the requirements specification and the code, which makes code maintenance very expensive. This work presents a proposal of a process that facilitates the explicit definition of traceability strategies and activities necessary to the use of traceability. The process also includes traceability project and validation strategy activities. As a case study, an instantiation process in a development environment Oracle is performed using the proposed process.

This thesis deals with the controlling environment in the Revenue Assurance team of the telecommunication company Vodafone Inc. Its main goals are the suggestion of realizing and implementation of a new controlling process in Revenue Assurance. The individual goals of the thesis are introducing the term Revenue Assurance, so that the reader would understand the basic connection, and explanation of understanding the Revenue Assurance concept in other companies. The term is further compared to other controlling concepts such as controlling, risk management and internal audit, and the main differences among them are stated. Additionally, it explains the connection between the Revenue Assurance concept and the Sarbanes-Oxley Act. This thesis' part is then followed by an explanation of understanding the Revenue Assurance concept in the telecommunication company Vodafone CZ. The key part of the thesis is the description of the suggestion, realizing and implementation of the control into the company process. This part is preceded by a descriptive part dealing with description of the chosen method and the analysis of a telecommunication environment. The final part then deals with the question if the control has been implemented successfully and how it was working during its existence. Finally, I state the benefit for the company according to the number of the cases and the revealed amount of revenue leakage.
