The testing process of a complex program managed with a version system and developed by a large team of international developers is a very lengthy and demanding task. In this paper, we present an automated testing infrastructure for OSCAR that rely on the virtualization of Linux computers. The virtualization layer is provided by the Linux-VServer project. The current design and implementation of the testing program will be presented from a developer point of view. Tests that can be made with the current implementation will be detailed as well as tests that can not be made given our technical choices.
