The superconducting magnet system of the Large Hadron Collider (LHC) has been fully re-commissioned ahead of the second run of physics production in 2015. More than 20,000 tests had to be performed and analysed to qualify around 1600 electrical circuits for operation at 6.5TeV. Automated analysis modules, defined directly by the various system experts in an English-like domain specific language (DSL), have been used successfully within the Accelerator Testing framework (AccTesting) during the latest re-commissioning campaign. For this, the experts define pass criteria for the powering tests, which are automatically verified, via assertion modules, in order for the test to pass. These modules currently analyse 4 test types executed for more than 1000 systems and even allowed experts to identify issues, which are missed by manual analysis during previous campaigns. This paper describes the first operational experience with such kind of analysis modules, as well as a follow-up analysis of the results compared with previous commissioning campaigns. The analysis looks at potential shortcomings of the framework and attempts to improve the dependability of automated analysis with regards to high current (>IkA) circuits of the LHC are outlined.
