Abstract

A system, method, and computer program product are provided for testing a network service associated with a communications network. In use, a network service to be tested is identified, the network service including at least one network service associated with a communication network. Further, test criteria associated with the network service to be tested is identified. Additionally, a test scenario is generated for testing the network service based on the testing criteria. Furthermore, a Software Defined Networking (SDN) controller is programmed such that: a request associated with the generated test scenario is sent to an ingress point associated with the network service; the request is received at an egress point of the network service, upon the request being processed utilizing the network service; and the request is passed back to a testing software module that initiated the request, the testing software module having knowledge of rules associated with the SDN controller for generating the testing scenario. Moreover, the request that is passed back to the testing software module that initiated the request is analyzed to test the network service. Still yet, a generated response to the request is sent to the egress point of the network service such that the network service is applied to the generated response and the generated response is passed back to the software testing module from the ingress point of the network service. The abovementioned sequence is repeated until testing is completed.
