    "description": "<p>Computergametechnologyisincreasinglymorecomplexand applied in a wide variety of domains, beyond entertainment, such as training and educational scenarios. Testing games is a difficult task re- quiring a lot of manual effort since the interaction space in the game is very fine grained and requires a certain level of intelligence that cannot be easily automated. This makes testing a costly activity in the overall development of games.</p>\n\n<p>This paper presents a model-based formulation of game play testing in such a way that search-based testing can be applied for test generation. An abstraction of the desired game behaviour is captured in an extended finite state machine (EFSM) and search-based algorithms are used to derive abstract tests from the model, which are then concretised into action sequences that are executed on the game under test.</p>\n\n<p>The approach is implemented in a prototype tool EvoMBT. We carried out experiments on a 3D game to assess the suitability of the approach in general, and search-based test generation in particular. We applied 5 search algorithms for test generation on three different models of the game. Results show that search algorithms are able to achieve reasonable coverage on models: between 75% and 100% for the small and medium sized models, and between 29% and 56% for the bigger model. Mutation analysis shows that on the actual game application tests kill up to 99% of mutants. Tests have also revealed previously unknown faults.</p>",
