How to deal with DETS?

Questions / Help
1

I’m working on stuff that implemented with DETS. Right now I put config of dets filename to #{env}.exs, for separate environment. but I feel that is not the way to open/close test dbfile in test mode. Even now I am not sure about do proper close file when supervisor is down.

my issue are

  • Test code that use of DETS (I use :dets.openfile when its process start)
  • Trigger DETS to properly close in any situation
