| Abstract | At the ISIS Neutron and Muon Source, we are in the process of upgrading from the LabVIEW-based SECI instrument control system to the new IBEX control system* based on EPICS**. It is crucial to the running of experiments that IBEX has a high uptime and few bugs. However, it is often not possible to test the system live on an instrument prior to an experiment and thus we must be sure that it is ready to go as soon as we have users. To test that we are correctly communicating with hardware we have built a framework to automate testing of EPICS IOCs using device emulators created using the LeWIS*** Python package. This lets us test that new drivers are functionally the same as those under SECI. To ensure that the full instrument control system stack is working as intended we are also using the Squish testing tool****. Whilst this is used by industry as a GUI focused tool we have used it in conjugation with a fully simulated IBEX installation to create system tests, letting us directly simulate the interactions a user has with IBEX and validate its behavior. This poster will present how using these tools has made IBEX a more robust system. | |
