1. A testing apparatus for identifying transient connection conditions constituting intermittent faults on connecting paths within a unit under test (UUT), the testing apparatus comprising:

  • a set of one or more testing modules, each testing module comprising;

    a set of stimulus circuits that are individually controllable as a source or sink of stimulus signals and are individually electrically connectable to one or more connection points in the UUT; and

    a set of intermittence-detecting circuits that are individually electrically connectable to each of the one or more connection points in the UUT;

    a logic circuit configured to perform the following;

    determine when a transient event has occurred at any one of the set of intermittence-detecting circuits to thereby trigger the testing apparatus;

    determine the one or more connection points within the UUT that triggered the testing apparatus to thereby identify an intermittent fault;

    assign a timestamp to each identified intermittent fault; and

    generate a set of data defining each intermittent fault for reporting to a testing apparatus controller; and

    an interface for electrically attaching at least one UUT to one or more of the set of testing modules, each UUT comprising a plurality of connection lines configured to connect electronic components.
