  Context. Considering the importance of software testing to the development of
high quality and reliable software systems, this paper aims to investigate how
can work-related factors influence the motivation of software testers. Method.
We applied a questionnaire that was developed using a previous theory of
motivation and satisfaction of software engineers to conduct a survey-based
study to explore and understand how professional software testers perceive and
value work-related factors that could influence their motivation at work.
Results. With a sample of 80 software testers we observed that software testers
are strongly motivated by variety of work, creative tasks, recognition for
their work, and activities that allow them to acquire new knowledge, but in
general the social impact of this activity has low influence on their
motivation. Conclusion. This study discusses the difference of opinions among
software testers, regarding work-related factors that could impact their
motivation, which can be relevant for managers and leaders in software
engineering practice.
