This thesis discusses software containers (Docker containers in particular) as a variant of server virtualization. Instead of virtualizing hardware, software containers rest on top of a single operating system instance and are much more efficient than hypervisors in system resource terms. Docker containers make it easy to package and ship applications, and guarantee that applications will always run the same, regardless of the environment they are running in. There is a whole range of use cases of containers, this work examines their usage in the field of software testing. The thesis proposes three main use case categories for running software systems in Docker containers. It introduces aspects for applications running in containers, which should give a better overview about an application setting within containers infrastructure. Subsequently, possible issues with testing software systems running inside Docker containers are discussed and the testing methods which address the presented issues are proposed. One proposed testing method was also used in the implementation of the framework for testing software running in Docker containers which was developed within this work.

The study aims at demonstrating that once knowledge is formalised, it is possible to reuse it, to perform inference, to process it throuch computers, and, what is more, it becames amenable to being communicated between people and software. Towards that, three ontlogies have been developed: OSOnto (Operating System Ontology) which represents concepts of the operating system domain, SwTO (Software Test Ontology) which deals with the software testing domain, and SwTOI (SwTO Integrated) which represents concepts of both the above domains in an integrated way. For implementing the ontologies, OWL DL as ontology specification language, Prot´eg´e as ontology edition environment and Racer as the main reasoner, have been used. A quantitative and qualitative evaluation of the SwTOI ontology has been performed. / Este trabalho reúne elementos de um estudo sobre representacão do conhecimento fundamentado em ontologias tendo como domínio alvo o teste do Linux. O estudo visa demonstrar que uma vez que o conhecimento é formalizado, é possível reusá-lo, realizar inferência, processá-lo computacionalmente, como também tornase passível de comunicação entre pessoas e software. Para tal, foram desenvolvidas três ontologias: a OSOnto (Operating System Ontology) que representa conceitos do domínio de Sistema Operacional, a SwTO (Software Test Ontology) que trata do dom´ıniodetestedesoftware, e a SwTOI (SwTOIntegrated) que representa conceitos destes dois domínios integrados. Para a implementação das ontologias foi utilizada OWL DL como linguagem de especificação, o Protégé como ambiente de edição e o Racer como principal raciocinador. Uma avaliação quantitativa e qualitativa foi realizada da ontologia SwTOI.
