You've flipped my statement which changes its meaning. I said I'd question the design of any code base that large. Some would pass that questioning. I did not say that all large code bases have questionable design. I won't debate a strawman anymore so I'll move on. Btw, are device drivers counted in that millions of lines of code? If so those are very independent things. This thread was about test coverage, how many of those millions of lines of kernel code are covered by a unit test? EDIT: so you agree with my original assertions that large test suites may not be worth the cost?
