   6test_description='Test the very basics part #1.
   7
   8The rest of the test suite does not check the basic operation of git
   9plumbing commands to work very carefully.  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 here.
