  Computer games are very challenging to handle for traditional automated
testing algorithms. In this paper we will look at intelligent agents as a
solution. Agents are suitable for testing games, since they are reactive and
able to reason about their environment to decide the action they want to take.
This paper presents the experience of using an agent-based automated testing
framework called \ivxr\ to test computer games. Three games will be discussed,
including a sophisticated 3D game called Space Engineers. We will show how the
framework can be used in different ways, either directly to drive a test agent,
or as an intelligent functionality that can be driven by a traditional
automated testing algorithm such as a random algorithm or a model based testing
algorithm.
