> Creating a mock is still better than not creating a mock to test against. With the mock you can create simulations, unit tests, coverage tests, static tests, formal verification. You did not understand what i wrote. With hardware, its just damn difficult to get accurate mocks. If the mock is wrong, all tests relying on it are not meaningful. If you ask me, QEMU doesn't even properly support emulating x86. Its just "good enough" to run common operating systems. You could try improving the support, maybe then you will realize how just damn difficult and undocumented this shit is, and you would understand why nobody wants to hear your crappy unit test evangelism.
