-test_description='Test the very basics part #1.
-
-The rest of the test suite does not check the basic operation of git
-plumbing commands to work very carefully.  Their job is to concentrate
-on tricky features that caused bugs in the past to detect regression.
-
-This test runs very basic features, like registering things in cache,
-writing tree, etc.
-
-Note that this test *deliberately* hard-codes many expected object
-IDs.  When object ID computation changes, like in the previous case of
-swapping compression and hashing order, the person who is making the
-modification *should* take notice and update the test vectors here.

-# If your shell fails this test, the results of other tests may be
-# unreliable. You may wish to report the problem to the Git mailing
-# list <git@vger.kernel.org>, as it could cause us to reconsider
