A test kit for a semiconductor package and a method of testing a semiconductor package using the same are provided. The test kit may include a pick-and-place tool for loading/unloading a semiconductor package, a head assembly for guiding a semiconductor package released from the pick-and-place tool, and a socket for receiving the semiconductor package from the pick-and-place tool. The method may include performing pre-alignment by inserting one or more slide posts of an alignment tool into a socket, releasing a semiconductor package through a package guider, and attaching the semiconductor package onto a socket.
