Systems and methods for replication of test results in a network environment are disclosed. Methods described may include recording network traffic in a first instance of a test case by a network emulator node emplaced in the network environment, recording a time at which a connection open at the network emulator node completes a communication task, and deriving an order of task completion for each extant open connection thereby, and detecting the occurrence of one or more events, such as a packet drop, a packet retransmission, or a packet delay, among other events. Replication, as described, additionally involves recording the nature of the event and identification information associated with the packet to which the event is detected to have occurred; and associating the one or more events with each of the packets recorded, on the basis of the identification information and event recording.
