Unreal ships an automated testing framework that runs inside the engine itself — no external test

Everything covered so far in this folder — Details customizations, factories, Editor Utility Widgets —

Every technique in the rest of this folder needs a board on the desk, or at minimum a physical binary running somewhere real. Unit Testing Firmware and Mocking Hardware sidestep that by pulling logic out from behind a seam and running it on the host — a deliberate, narrow substitute for one driver's register interface. Simulation is a different move entirely: instead of extracting the logic, it models the chip, and runs the actual, unmodified cross-compiled firmware.elf against that model — the same instruction stream, the same startup code, the same register pokes, executing against a virtual STM32 instead of a real one.

There is a tool that finds real defects, requires no new install, no configuration file, and no CI integration beyond a flag already accepted by the compiler you are already invoking on every build — and most projects run it in a mode that throws its findings away. That tool is the compiler itself. arm-none-eabi-gcc already builds a fully type-checked internal representation of your program to generate code from; a warning is analysis it already did, offered back to you, and the default build configuration in a great many embedded projects is -Wall at best, or nothing at all, which means the cheapest static analysis available is routinely left switched off.
