A method for realizing a test is provided. The method includes receiving a test signaling and a planning parameter of an internet protocol (IP) bearer network; initiating a test service on the IP bearer network according to the test signaling and the planning parameter of the IP bearer network; and obtaining a performance indicator of the IP bearer network according to the running situation of the test service. An apparatus for realizing a test is also provided. A test service is initiated on the IP bearer network according to the planning parameter of the IP bearer network; and a performance indicator of the IP bearer network is obtained according to a running situation of the test service. According to the performance indicator, it is determined whether the current IP bearer network satisfies the performance requirements of the communication network planning model.
