The Large Hadron Collider (LHC) at CERN requires many systems to work in close interplay to allow reliable operation and at the same time ensure the correct functioning of the protection systems required when operating with large energies stored in magnet system and particle beams. The systems for magnet powering and beam operation are qualified during dedicated commissioning periods and retested after corrective or regular maintenance. Based on the experience acquired with the initial commissioning campaigns of the LHC magnet powering system, a framework was developed to orchestrate the thousands of tests for electrical circuits and other systems of the LHC. The framework was carefully designed to be extendable. Currently, work is on-going to prepare and extend the framework for the re-commissioning of the machine protection systems at the end of 2014 after the LHC Long Shutdown. This paper describes concept, current functionality and vision of this framework to cope with the required dependability of test execution and analysis.

The Large Hadron Collider (LHC) at CERN requires many systems to work in close cooperation. All systems for magnet powering and beam operation are qualified during dedicated commissioning periods and retested after corrective or regular maintenance. Already for the first commissioning of the magnet powering system in 2006, the execution of such tests was automated to a high degree to facilitate the execution and tracking of the more than 10.000 required test steps. Most of the time during today’s commissioning campaigns is spent in analysing test results, to a large extend still done manually. A project was launched to automate the analysis of such tests as much as possible. A dedicated Java embedded Domain Specific Language (eDSL) was created, which allows system experts to describe desired analysis steps in a simple way. The execution of these checks results in simple decisions on the success of the tests and provides plots for experts to quickly identify the source of problems exposed by the tests. This paper explains the concepts and vision of the first version of the eDSL.
