Unit testing on limited memory Microcontoller often require expensive ICE with RAM buffers.IDEs often did not provide inbuild unit testing and static analysis tools in case of micro controllers developmet IDEs .Alternative is to use QMU simulator for slected Micro contoller archetecture and use ceedling project on Eclipe to create and test code,run test and genrate test port

Below example shows a sample project file used for running a ceedling unit test
