6 test_description='Test the very basics part #1.
7
8 The rest of the test suite does not check the basic operation of git
9 plumbing commands to work very carefully. Their job is to concentrate
10 on tricky features that caused bugs in the past to detect regression.
11
12 This test runs very basic features, like registering things in cache,
13 writing tree, etc.
14
15 Note that this test *deliberately* hard-codes many expected object
16 IDs. When object ID computation changes, like in the previous case of
17 swapping compression and hashing order, the person who is making the
18 modification *should* take notice and update the test vectors here.
