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.
