Abstract: A test environment configuration apparatus and a method of operating a network simulation apparatus using the test environment configuration apparatus are disclosed. The test environment configuration apparatus includes a scenario configuration module, a simulation initiation module, and a monitoring module. The scenario configuration module configures a simulation scenario performed on one or more virtual machines and one or more simulation nodes generated by a network simulator. The simulation initiation module controls the internal applications of the virtual machines corresponding to the simulation nodes, and generates a simulation initiation signal to run a network simulation for testing a communication connection between the simulation nodes. The monitoring module monitors the network simulation and the internal applications, and provides the results of the monitoring to a user.
