If you go to the Vandenberg AFB launch site, they pretty much tell the world months in advance of these launches. http://www.spacearchive.info/vafbsked.htm

FOT&E (Fleetwide Operational Testing and Evaluation) missile launches are a routine part of Minuteman operations. Typically we test two or so missiles a year randomly selected from the 450 remaining (soon to be 400) Minuteman IIIs on alert.

The warheads are removed obviously and replaces with an instrumented reentry vehicle.
