It is a test devised by the mathematician, cryptographer and computer scientist Alan Mathison Turing in the mid-twentieth century to check if a computer could be equated in intelligence to a human. It started from the assumption that if a person chats with another and with an artificial intelligence he should be able to distinguish who is human and who is not; But if it doesn't then the machine would have attained the human ability to converse like an intelligent being.
