The ASVAB is a timed multi-aptitude test, which is given at over 14,000 schools and Military Entrance Processing Stations (MEPS) nationwide and is developed and maintained by the Department of Defense.

Although the test is administered by the military, it is not (and never has been) a requirement that a test-taker with a qualifying score enlist in the armed forces.  While the military uses this test for admittance this test can also be used to gauge your aptitudes in vocations outside of military service.
