Their job is to concentrate 10on tricky features that caused bugs in the past to detect regression. 11 12This test runs very basic features, like registering things in cache, 13writing tree, etc. 14 15Note that this test *deliberately* hard-codes many expected object 16IDs. When object ID computation changes, like in the previous case of 17swapping compression and hashing order, the person who is making the 18modification *should* take notice and update the test vectors
