The invention relates to an automatic test system for access network equipment. The system comprises a client, a server and a tester; the server establishes communication connection with the access network equipment, obtains a test motion which needs to be executed by the access network equipment, and sends a message including the test motion to the client; the client determines a test case which needs to be executed, sends a calling instruction of the test case to the server, receives a packaging function returned by the server, analyzes the packaging function to obtain an original test function, and sends the original test function to the tester; the tester converts the original test function into a corresponding target test function, and sends the target test function to the access network equipment; and the access network equipment executed a corresponding test operation according to the target test function, generates a test log according to an execution result of the test operation, and returns the test log to the client.
