As I mentioned in an earlier email, I plan to set an environment variable for the algorithms in use and then do something like: test "$tree" = "$(test-tool hash-helper --output known-tree)" where "known-tree" is some key we can use to look up the SHA-1 or NewHash value, and we've specified we want the output format (as opposed to input format or on-disk format). > When we add NewHash, we get to add an "else if".

I agree that this test needs to be updated for NewHash, but since we haven't decided what that's going to be, it makes sense during development to still test the rest of the code if possible so that we know what does and doesn't work. This is a first step in making it obvious what doesn't work, and when we know what the data is supposed to be, we can adjust it by fixing the tests so that it works in all cases. -- brian m. carlson: Houston, Texas, US OpenPGP: https://keybase.io/bk2204
