Towards Trustworthy Testbeds thanks to Throughout Testing

International audienceWhen using testbeds in the context of experimental computer science, theability to produce trustworthy and reproducible experiments results dependsgreatly on the trustworthiness of the infrastructure itself. Unfortunately,several factors many issues such as software misconfiguration, hardwareheterogeneity, or service failures, can remain undetected and affect thequality of experimental results. This paper presents the design andimplementation of an automated testbed testing framework. This framework wasdeployed in the context of the Grid'5000 project, and uncovered more than onehundred of issues
