Just to add to what Maha said, its usually safer with a faction (even if they offer it after certain time of service) because if you board someone's ship/vehicle, they can trap you in it. So just be careful.

You get tested by other players in game or purchase a Force Detector.
This is not the place to find out if you are Force Sensitive. You can try looking in the Commerce forum to see if anyone is offering free Force testing or selling a Force Detector.
Also, if you join a faction, then they may offer to have you tested.
