The commissioner of the thesis was Digia Plc and the target of the thesis was to research and improve automated testing performed by the software developers. The main topics of the thesis were research, development and training. Various technologies were evaluated in order to find good set of tools to support the teams. Trainings were arranged related to these technologies and tools for the teams. In addition to that, there were two surveys that were used to evaluate how the software developers felt about automated testing. A great deal of attention was given to various problems and challenges that could hinder testing. Some of the teams were more active in using automated testing; however, in general the developers felt that the automated testing makes sense and helps them in their daily work. Different teams had slightly different focus on their testing effort, depending on the needs of the team. It was observed that introducing automated testing into a legacy application is not an easy task and it might require some unconventional design choices. The tests also require attention and maintenance as the system evolves and changes. During the research an improvement in perceived quality of the software was observed. The developers gained a better understanding how the components of the system work together and had less defects in their code. The difference of regression rate between the developers also decreased.
