With a  "one size fits all" test, one can comfortably check a box and
move on, thats not reliability testing.

Pick the test temp range that accelerates the use temperature of the assembly.
Pick a vib test profile that suits the use profile of the assembly.
Without going into a science project, you can do a rough linear
extrapolation of test to use conditions with acceleration factors.
