TL, DR: just follow [tests](tests) folder as examples In this folder we have rusEFI unit tests using https://github.com/google/googletest Unit tests are not aware of ChibiOS or ARM or else, they are just plain C/C++ which you build for your desktop, not your MCU. 1. Run 'make' to build desktop binary. 1. Execute rusefi_test binary on your PC/Mac, it's expected to say SUCCESS and not fail :) Googletest will also print results summary.
