The invention provides a method and a device for automated test of a communication protocol module test architecture. The method includes compiling a to-be-tested protocol module subjected to protocol source code change so as to generate an executable object file of the protocol module; matching a corresponding protocol with the executable object file according to the generated protocol module; organizing source data into a message according to the corresponding protocol; sending the message to the protocol module and utilizing the protocol module for analyzing the message so as to obtain result data; comparing the result data with the source data, judging that the test is qualified if yes, and judging that the test fails if not. The method solves the problem of low manual test efficiency.
