TL, DR: just follow [tests](tests) folder as examples.
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.
1. To run only one test uncomment and modify [main.cpp](https://github.com/rusefi/rusefi/blob/master/unit_tests/main.cpp) line ``::testing::GTEST_FLAG(filter)``
