In a method of service emulation, a plurality of messages communicated between a system under test and a target system for emulation are recorded in a computer-readable memory. Ones of the messages are clustered to define a plurality of message clusters, and respective cluster prototypes are generated for the message clusters. The respective cluster prototypes include a commonality among the ones of the messages of the corresponding message clusters. One of the message clusters is identified as corresponding to a request from the system under test based on a comparison of the request with the respective cluster prototypes, and a response to the request for transmission to the system under test is generated based on the one of the message clusters that was identified. Related computer systems and computer program products are also discussed.

Systems and methods for automatically generating message prototypes for accurate and efficient opaque service emulation

In a service emulation method, a transaction library storing a plurality of messages communicated between a system under test and a target system upon which the system under test depends is accessed responsive to receiving a request from the system under test. One of the messages stored in the transaction library is identified as corresponding to the received request based on a distance measure therebetween, and a response to the received request is generated using the one of the messages that was identified. Related systems and computer program products are also discussed.
