What do game developers test in their products?

Context: Software projects often have four objectives; to produce the required functionality, in budget and in schedule, with acceptable quality. That statement may be true for most of the ordinary software development projects, but are these objectives enough for game development, where creativity and artistic aspects have a major role? Goal: We analyze how game developing organizations test their products, what are their main test objectives and how they perceive themselves in the software business. Method: We interviewed seven game development teams from different companies and studied how they test their products with grounded theory approach. Results: Our results suggest that game developers focus on soft values such as game content or user experience, instead of more traditional objectives such as reliability or efficiency. Conclusions: Game developers have similar, but not fully comparable to software industry, set of priorities in their software testing and quality assurance approaches.
