Any sort of missile test undergoes extensive ground test at first. For any BMD, the seekers undergoes extensive test even before integration in missile.
If any missile gets inducted and goes into series production, then its tests depends on user. User generally does one or two test at max in a year. So missile testing is not like rifle testing. Its ground testing is more important then flight test.
