1. A computer workstation having functional logic thereon, the functional logic defining a tester state browser for interfacing with test equipment, the tester browser comprising: a set of plugins associated with one or more subsystems of the test equipment, the set of plugins indicating how to obtain, display and edit information for the one or more subsystems of the test equipment; a descriptor file describing an architecture of the test equipment and designating one or more of the set of plugins to corresponding one or more of the subsystems of the test equipment; a navigation module that determines the architecture of the test equipment, reads the descriptor file to identify ones of the set of plugins and determine how to display a map of the architecture of the test equipment, and displays in the map a set of drill-down mechanisms each associated with different ones of the subsystems of the test equipment, wherein each drill-down mechanism invokes the plugin associated with its corresponding respective subsystem.
