Ideally, no... and there are some things in a package, such as synopsis and description, which do not affect the build; I suspect it would take considerably more fiddling to exclude tests derivation hash calculation... > Should it ever affect a package's reproducibility? Should build-time tests affect reproducibility? No, surely not! Do they in practice? Most definitely yes. :( > Please bear with me as I again belabor the same point without receiving > public support. Building packages should be separate from testing them. In general, I agree... sort of. I do see value in build-time tests preventing a build from succeeding... being a way to ensure that a broken build does not actually get distributed. You could completely separate out the tests, and set up some other mechanism to prevent broken things from getting distributed, but that is considerably more complicated. I guess the question comes down to which corner-cases do you choose to cater to? live well, vagrant
