Wei Huang commented on YUNIKORN-1703:
-------------------------------------
Context: during writing a unit test for plugin mode's main.go, I met some
tricky issue:
{{2023-04-20T18:02:00.931-0700 ERROR shim/scheduler.go:219 failed to

I guess this is b/c the unit test setup cannot fully simulate a real env, so I
tried to enable testMode=true to bypass it, but it turns out testMode is
hard-coded to false.
