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. | |
