A circuit testing and control approach involves configurable switch control for automatically detecting and routing test signals along a plurality of test circuit paths. According to an example embodiment of the present invention, graphical user interface (GUI) (240) includes stored computer-executable code that, when executed, causes a micro-computer circuit to send configuration signals to a microcontroller (220). A configurable circuit (215) coupled to the microcontroller is then configured by the microcontroller, in response to the configuration signals, for routing test signals using controllable switches. In one implementation, the configurable circuit includes circuits on inter-connectable circuit boards (210, 250, 260), with sense nodes for detecting the presence of an inter-connectable circuit board coupled to another. In response to the detected presence (or lack thereof), the controllable switches control the routing of the test signals between the inter-connectable circuit boards. The configuration signals are used for one or more of actively controlling the microcontroller, programming the microcontroller (e.g., storing program code therein) or requesting data from the microcontroller. With these approaches, automatic switching of test signal paths, on an individual circuit and in connection with other circuits, is achieved without necessarily physically accessing the configurable circuit.
