Network testing system and method of using
A network testing system includes a non-transitory computer readable medium configured to store instructions thereon; and a processor. The processor is configured to execute the instructions for retrieving a call graph; identifying decision branches within the call graph; and generating a valid request payload for each of the decision branches. The processor is configured to execute the instructions for generating an invalid request payload for each of the decision branches; instructing an orchestrator to test a device under test (DUT) using each of the valid request payload and the invalid request payload; comparing responses received from the DUT to each of the valid request payload and the invalid request payload with expected responses; and determining that the DUT includes a failure in response to a determination that any of the responses received from the DUT fail to match a corresponding expected response of the expected responses.
