A network testing system includes one or more test devices each including a media-specific testing module and a processing device with a network interface, wherein the processing device is configured to test a network with the media-specific testing module; one or more servers configured to receive test results from the test of the network either directly from the one or more test devices or an intermediate data source communicatively coupled to the one or more test devices; and a validator module executed on the one or more servers configured to perform automated post-processing on the test results to compare the test results to a pre-defined Method of Procedure (MOP), to auto-correct one or more errors in the test results, and to provide a report based on the comparison.
