I have a SOF application built for EHR systems like Cerner, EPIC, Athena etc. The application runs well on sandbox environments. However, when I tried to check if the app is ready, before going for non-production and production environment, using open EMR. I encountered a strange issue where the application authenticates twice in open EMR, once before launch (EHR login) and once during launch (when clicked on launch). I am afraid that the same would happen when deployed to an actual EHR. (Open EMR is considered as the production version of Cerner and EPIC)
Even if I think it's a bug or a feature from openEMR, is there a way to test my app in any production similar environment of EHR (not sandbox)? Please suggest!
