Comparing Black- and White-box testing environments using mixed research methods and AHP

Abstract

With the intent of cost reduction, flexibility in management, decreasing complexity, improving efficiency and more, the company for which this thesis work was performed, decided to investigate on the two radio unit software testing environments (black- and white-box) which were presumed to overlap. Since removing one environment or integrating them into one can lead to saving a lot of resources, a decision was made to assess their feasibilities. In order to do this study, quantitative and qualitative research methods are mixed, two questionnaires are done for revealing the testers opinions and neglected issues. The questionnaires helped the author of this thesis to find a suitable gateway through a large amount of internal documents and establish two interviews with key persons inside the R&D department. Moreover, the Analytical Hierarchy Process (AHP) is applied to this multi-criteria decision making problem in order to prioritise these two testing environments. The thesis strives to supply a fair judgment in comparing these two environments and their integration feasibility. It also tries to disclose their intangible properties.
