One of the QualiPSo Project activities is to evaluate the quality of the developed test sets by the FLOSS community. This work is part of the QualiPso Project and shows the results of the use of structural test criteria as a functional test sets quality measure to identify the state-of-the-practice of performed test activities by free software communities. Furthermore, this work contributes to establish an incremental test strategy to improve the test sets. / O projeto QualiPSo (Quality Platform for Open Source Software) tem por objetivo investigar produtos de software de código gratuito/livre/aberto (Free/Libre/Open Source Software FLOSS) para definir requisitos de qualidade que são importantes para se estabelecer a confiabilidade desses produtos. Uma das atividades do projeto QualiPSo visa avaliar a qualidade de conjuntos de teste desenvolvidos pelas comunidades de software livre. Esta dissertação de mestrado está inserida neste contexto e apresenta os resultados do emprego de critérios de teste estruturais como uma medida da qualidade de conjuntos de teste funcionais visando a identificar o estado-da-prática das atividades de teste desempenhadas pelas comunidades de software livre, bem como, a contribuir no estabelecimento de uma estratégia de teste incremental para evoluir os conjuntos de testes.

Main topic of this thesis is evaluation of user interfaces of learning management systems (LMS). It is the users and their interaction with the system who are the focus of user interface design within the field of Human Computer Interaction (HCI), and that is why user experience was taken into account for interface evaluation. The aim of the thesis was proposition of function criteria field that reflect users' requirements on the system and that can therefore serve as a basis for partial LMS evaluation. Within the scope of HCI interdisciplinarity, we focused on technical-psychological view (computer - human), complemented by the field that reflects the very purpose of LMS - pedagogical process. We believe that combination of general function criteria, which can be applied to any system, and learning content criteria is crucial for LMS evaluation, together with criteria concerning distribution forms and work methods. Based on defined areas, LMS Unifor courses from 2012- 2014 period of time and LMS Moodle courses from 2015-2017 period of time were evaluated using qualitative and quantitative research methods. The output of the research is a set of function criteria, which we regard to be elementary and suggest to be taken into account when considering a LMS.
