1. A test system for obtaining test results characterizing at least part of a network-under-test, the system comprising:

  • a local test device comprising;

    a firmware module that initiates a test sequence on the network-under-test only following receipt of external instructions therefor, the test sequence leading to the production of test measurements related to the network-under-test and unrelated to performance of the local test device, wherein the firmware module cannot process the test measurements to provide the test results and wherein the external instructions are received over a local interface of the local test device connected to a local terminal temporarily co-located with the local test device; and

    a network interface (NI) module comprising the local interface and at least one physical port connectable to the network-under-test, the at least one physical port being used for initiating the test sequence;

    a test processing agent, decoupled from the network-under-test for;

    sending to the local terminal, prior to the external instructions being received at the local device, at least a portion of the external instructions for initiating the test sequence on the network-under-test, the test sequence leading to the production of the test measurements related to the network-under-test;

    receiving the test measurements following the initiation of the test sequence by the local test device;

    processing the test measurements related to the network-under-test into the test results; and

    allowing access to the test results.
