Systems and methods for providing a boundary scan test of a wired or wireless network having a plurality of network nodes are presented. The system includes a test station communicatively coupled with the network. The test station creates a MAC layer scan test route sequence that includes each link in the network and is independent of the routing mechanism and protocol used for the network. The test station also creates a test agent that is configured to traverse each link in the scan test route sequence. The test agent is then deployed on the network and information about a link is reported back to the test station after the test agent examines the link. The scan test route sequence can be created by sending out a series of broadcast messages from one or more nodes in the network, sequentially applying a network tour to cover the entire network, or performing a depth first search on the entire network.

A substrate tester and method of testing are disclosed in which the tester moves a substrate to be tested into a precise location within the tester prior to making contact with fragile tester pins.
