+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.
