Abstract

A system and method for creating a test executive sequence configured to perform one or more hardware switching operations. A user interface for configuring a first test executive step (i.e., a particular step) in the test executive sequence may be displayed. User input specifying one or more hardware switching operations may be received to the user interface. The first test executive step may be configured to perform the specified one or more hardware switching operations during execution of the test executive sequence. The user interface may enable the user to configure the first test executive step to perform the specified one or more hardware switching operations without requiring user programming or without requiring the user to write source code.
