Abstract
A method and system for testing a physical system including a number of input channels for receiving physical inputs, using load testing, comprising: intercepting at least a portion of the input channels; replacing at least a portion of the physical inputs of the intercepted input channels with one or more emulation programs, wherein the emulation programs include parameters which allow to control outputs of the one or more emulation programs to the intercepted input channels; configuring a functional test in a load testing software tool to drive execution of the one or more emulation programs; randomly generating outputs simulating the physical inputs, from the one or more emulation programs, by executing the load testing software tool; collecting data from the execution of the one or more emulation programs as the load testing software tool executes; and analyzing the collected data for presence or absence of deadlocks or race conditions.
