I will add unit tests to your embedded c firmware without hardware

Your firmware has no tests, and every change feels risky?

I add host-based unit tests to embedded C code, so you can test logic on a PC without any board.

I am a Japanese embedded engineer with 20 years of experience at major electronics makers and an automotive Tier-1 supplier (airbag ECU, EV interface box, construction machinery).

What I will do:

- Analyze your code and choose the modules worth testing first

- Mock hardware registers and drivers so tests run on a PC

- Write tests with Unity, CppUTest or GoogleTest, including edge cases

- Set up a simple build script or CI (GitHub Actions / GitLab CI)

- Report bugs found during testing

What you get:

- Test code and mocks that build and run on your PC

- Coverage report

- A short guide so your team can add more tests

Supported: C / C++, Renesas RX / RH850 / V850, STM32 / ARM Cortex-M, embedded Linux, uITRON and bare metal.

I use modern AI-assisted tools to work fast, and I personally review every test for correctness.

Please message me with your MCU, code size and build environment before ordering.
