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. |
