which is best way for capture and reply in embedded system testing?
/embedded/ software testing?
that can be extremely challenging, and I'm afraid we don't know what you mean here.
If you can drive the device through inputs and outputs (plugged in to a cable) then you can drive it as sort of a black box. Another option is to use a simulator and drive the laptop. Good luck; tell us more about the device and I can give a better answer.
As Matt says, embedded systems are not easy to work with. The only way we have been able to automate them is create a device simulation, and this only manages to simulate a subset of the code.
