A method of testing a communication network. The method comprises providing network communication service to communication service subscribers by a first set of computing resources that are part of a communication network, replicating communication data packets, directing the replicated communication data packets to the first set of computing resources and to a second set of computing resources that are part of the communication network but which do not provide network communication service to communication service subscribers, introducing a random error into the second set of computing resources, capturing by a testing application executing on a server computer the outputs from the second set of computing resources after processing the replicated communication data packets in the context of the random error, analyzing the captured outputs by the testing application, determining that the captured outputs indicate a failure by the testing application, and taking action by the testing application.
