Right what needs to be tested is the kernel functionality and that the tools call correct syscall with correct paramters, these are two different things. But still as far as I can see the easiest way is to run the whole test and switch between the tool it uses which is just a few lines of code. How do you plan to test that ip does what it should? Run it under strace and grep for the syscall and check the parameters? That sound fragile to me. Or is there a better way? > The idea being that you don't exactly need to "brute force" test > everything everytime - the kernel functionality doesn't change > based on what utility uses the unshare() syscall. > I (in ltp-unrelated activities) found out that this approach gives > the best coverage / time / maintenance ratio. Agree that the kernel functionality is the same. But how does having two different testcases one for kernel functionality and one for ip decrease maintenance ratio? This soulution would IMHO be more complicated. The coverate should be same. The only aspect in which this solution is likely better is test runtime, but that shouldn't be a problem because these testcases does not take long time.
