Test case generation of embedded real-time systems with interruptions for FreeRTOS

Abstract

This paper discusses issues raised in the construction of test models and automatic generation of test cases for embedded real-time systems with interruptions that can run on the FreeRTOS operating system. The focus is on the use of symbolic transition systems (STSs) as the formalism from which test cases are generated by using the STG tool. The solution presented considers a test case execution model for real-time systems with interruptions that can be based on the integrated use of FreeRTOS components. A case study is presented to illustrate all steps from the construction of the test model to test case generation. © 2009 Springer-Verlag Berlin Heidelberg.
