Unit testing and emulating hardware


We are trying to set up unit testing for our project however had trouble running it on the nrf51 board and decided to run it natively on a windows platform.

My question is what is the best unit testing framework for nrf51 projects? We are currently trying to use unity & CMock.

is there an emulator for the NRF51? Which emulator is the best one to use?

We also use the S130 soft device
