The subject of this thesis is testing of the information system. The testing is viewed as a specific part of the project, which should be described by a process. In the first part of this thesis the general concept of testing is described, it also contains basic ideas about its importance and basic concepts related to it. There are defined basic categories and testing techniques. There is also suggestion of structure of test team, individual roles within the team and general model of testing. The second part is a practical one, which deals with the project of development of payment systems within Česká pojišťovna. There are defined main problems in testing, which are solved by the proposed changes -- new organization of the project, new roles and new processes. In conclusion, these changes are evaluated whether they are positive or negative, and whether problems were resolved.

This thesis deals with the issue of process optimalization in the field of test discipline which is a fundamental part of software development. An approach providing improvement of test processes is applied in the environment of a test department in a selected company. Concept of raising process capability and maturity presented in CMMI model is used for this purpose. The first goal of the thesis is a provision of theoretical background devoted to software testing, process approach and capability and maturity models, that will accommodate enough with the clarity of the document text, as well as to provide insight into the whole subject. Theoretical interpretation will be compiled using on-line resources available for free, author's bachelor thesis and facts obtained through the studies and from educational materials. Attention will be focused on the definition of important facts and mutual relationship between the areas of interest. Description of initial state, changes carried out and current state of organizational structure, processes and documentation in the test department of the company was selected as a following goal. Process models consisting of diagrams, description tables and textual characteristics of identified processes will be created. Structure of documentation and of its parts will be accentuated through the description of documentation state and changes, furthermore a chronological sequence of taking the documents into practice and explanation of its importance in testing will be present. In order to offer a comprehensive view, a description of organizational structure and department member's competence will be available. As the last goal, arrangement proposal to obtain a higher process maturity and further improvement of documentation and organizational structure was chosen. Process areas and recommendation related to the processes of test discipline will be selected from the CMMI model. The selected content will be interpreted as to form a partial steps for direct use in test department. Appropriate sequence of the steps will also be set to serve well the purposes of the department. Beyond the scope of arrangement proposal, separate recommendations in areas of organizational structure, processes and documentation will be present. The thesis summarizes key facts about and arrangements made in organizational structure, processes and documentation of the test department in the selected company in the period of last two years. The contribution lies further in the creation of so far absent process models of the test department which capture the form of test processes in two points in time, and especially in the complete arrangement proposal aiming to raise process maturity and optimize organizational structure and documentation.

Sistemas embarcados estão mais complexos e são cada vez mais utilizados em contextos que exigem muitos recursos computacionais. Isso significa que o hardware embarcado pode ser composto por vários processadores, memórias, partes reconfiguráveis e ASIPs integrados em um único silício. Adicionalmente, o software embarcados pode conter muitas rotinas de programação executadas sob restrição de processamento e memória. Esse cenário estabelece uma forte dependência entre o hardware e o software embarcado. Portanto, o teste de um sistema embarcado compreende o teste do hardware e do software. Neste contexto, a reutilização de procedimentos e estruturas de teste é um caminho para se reduzir o tempo de desenvolvimento e execução dos testes. Neste trabalho é apresentado um método de teste integrado de hardware e software. Nesse método, casos de teste desenvolvidos para testar o software embarcado também são usados para testar o seu processador. Comparou-se os custos e cobertura de falhas do método proposto com técnicas de auto-teste funcional. Os resultados experimentais demonstraram que foi possível reduzir os custos de aplicação e geração do teste do sistema usando um método de teste integrado de software e hardware. / Embedded Systems are more complexity. Nowadays, they are used in context that requires computational resources. This means an embedded hardware may be compound of several processors, memories, reconfigurable parts, and ASICs integrated in a single die. Additionally, an embedded software has a lot of programming procedures, which is under processing and memory constraints. This scenario provides a stronger connection between hardware and software. Therefore, the test of an embedded system is the test of both, hardware and software. In this context, reuse of testing structures and procedures is one way to reduce the test development time and execution. This work presents an integrated test of software and software method. In this method, test cases developed to test the embedded software are also used to test its processor. We compared the costs and fault coverage of our proposed method with techniques of functional self-test. The experimental results show that it is possible to reduce the implementation and test generation costs using an integrated test of software and hardware.

The subject of this diploma thesis is the design of a single-purpose machine for automatic testing of pneumatic fittings. Pneumatic fittings used in brake systems are subject to high technical requirements and 100% tightness control in production. In this case, manual testing is not effective and the goal is to automate the process. The theoretical part presents pneumatic mechanisms, analysis of the tested pneumatic fitting with technical parameters, the possibility of tightness testing, use of sensors, and rotary tables. In the practical part, a systematic analysis of the problem was performed, according to which the overall design proceeded. Subsequently, the design of the complete machine containing individual nodes is processed, supplemented by the necessary calculations. The conclusion of the thesis contains an evaluation of the whole project.

The complexity demanded by the construction of this layer of software is high, which also increases the complexity of testing. The importance of software testing and its relationship with quality should be emphasized, since this type of system still has a high degree of complexity inherent to its development, mainly due to its specification is recent, and by proposing innovative features. Besides being considered a critical software, since failures in the implementation of middleware can compromise the success of Digital TV as a whole. The middleware is a key player within a Digital TV system since it is he who dictates the rules so that applications can be run on the platform. Thus, the correctness of middleware is of vital importance to enable interactive applications to run successfully. The project CDN Ginga (Ginga Code Development Network) is responsible for developing collaborative and distributed a reference version for PC Ginga. This implementation is based on software components and open to universities and companies. In this context, this paper proposes a process for verification and validation of middleware Ginga, to be deployed in parallel to the process of project development Ginga CDN, facing the common core components (Ginga-CC). For this purpose, we defined a set of tests, which aim to check the operation of middleware, as well as validate the different configurations of components, from middleware Ginga CDN generated by the network. / O middleware Ginga é a especificação oficial e padronizada de middleware para o Sistema Brasileiro de TV Digital. A complexidade demandada na construção dessa camada de software é alta, o que também aumenta a complexidade de se testar. A importância do teste de software e sua relação com a qualidade devem ser enfatizadas, visto que este tipo de sistema ainda possui alto grau de complexidade inerente ao seu desenvolvimento devido, principalmente, por sua especificação ainda ser recente, e por propor funcionalidades inovadoras. Além de ser considerado um software crítico, pois falhas na implementação do middleware podem comprometer o sucesso da TV Digital como um todo. O middleware é uma peça chave dentro de um sistema de TV Digital uma vez que é ele quem dita às regras para que as aplicações possam ser executadas na plataforma. Dessa forma, a corretude do middleware é de vital importância para permitir que as aplicações interativas sejam executadas com sucesso. O projeto Ginga CDN (Ginga Code Development Network) é responsável pelo desenvolvimento colaborativo e distribuído de uma versão de referência para PC do middleware Ginga. Essa implementação é baseada em componentes de software e aberta para universidades e empresas. Neste contexto, este trabalho propõe um processo para verificação e validação do middleware Ginga, para ser implantado em paralelo ao processo de desenvolvimento do projeto Ginga CDN, voltado para componentes do núcleo comum (Ginga-CC). Para tanto, foram definidos um conjunto de testes, os quais visam verificar o funcionamento do middleware, bem como, validar as diferentes configurações de componentes, desde middleware, geradas pela rede Ginga CDN.
