Software quality attributes are properties that reflect the quality of a software system, and Non-functional requirements (NFRs) are the specifications that define how a software system should perform to reach a desired level of goals of the quality attributes.The evaluation of quality attributes is important to show the effectiveness of a system in meeting customers' NFRs. Continuous integration (CI) environments have emerged as powerful platforms for organizations to improve software quality through automated software verification and validation.Despite this, there is a growing need for evaluating quality attributes that is often met by in-house development of metrics and tools.This highlights the importance of quality attributes for software product quality. This thesis investigates the association between quality attributes and components of a CI environment, as well as how to utilize these components for evaluating software quality attributes.The focus is on improving the knowledge of the evaluation and providing specific recommendations for companies to enhance their CI environments for higher demands of quality evaluation.The contributions of this thesis include a better understanding of the relationship between quality attributes and CI components, and a set of practical guidelines for companies to effectively leverage CI for quality attribute evaluation. The studies in this thesis utilized mixed methodologies, including a systematic literature review, a multi-case study conducted in four software development companies, and an synthesis of the collected data.The multi-case study provided a comprehensive overview of practices for quality attribute evaluation and how CI components can generate data to support the evaluation of specific attributes.The synthesis study presents a maturity model based on the collected data from both academia and industry, and the model can aid organizations in assessing their current level of maturity in utilizing CI environments to identify potential improvements.The results in these studies show the capabilities of different components of a CI environment and how these components can be used to support the evaluation of quality attributes.While the use of CI environments for the thesis topic offers benefits, it also presents several challenges, for example, the challenge to identify effective quality metrics. In conclusion, this thesis contributes to the understanding of the use of CI environments for evaluating software quality attributes.The results suggest that CI environments can be an effective approach for quality attribute evaluation, but suitable metrics need to be considered to ensure accurate and meaningful evaluation results. Furthermore, the thesis presents areas for future research, such as the use of machine learning techniques to improve the accuracy of quality assessment using CI environments.
