How often do kernel hardware tests run?
I'm wondering why python was used since I wouldn't expect the mocked drivers to be performant. Both, runtime and startup. But if this is only about initialization, maybe it is fast enough.

During testing, you want to test code to be as simple as possible and as readable as possible, the least thing you want is a bug in your mock driver.

The answer to that is currently nobody in fact knows the answer to that question. Multi different companies run Linux kernel testing. If there is no error lot of them don't report their runs.

Linux testing does need a lot more work.

I agree, one more reason to use a readable language with types and sane static validation.
Probably "go" would have been a fair choice.
But I guess python was chosen because it is preinstalled everywhere.

Having had a (very) brief look at the code*, it is clear that it makes use of python3's type annotations and is therefore statically checkable with mypy**.

Why there are cows in article thumbnail?

It's the result of most articles being too technical and the concepts in question being so abstract.
