The support for multiple test prerequisites added by me in "test-lib: Add support for multiple test prerequisites" was broken. The for iterated over each prerequisite and returned true/false within a case statement, but since it missed a return statement only the last prerequisite in the list of prerequisites was ever considered, the rest were ignored. Fix that by changing the test_have_prereq code to something less clever that keeps a count of the total prereqs and the ones we have and compares the count at the end. This comes with the added advantage that it's easy to list the missing prerequisites in the test output, implement that while I'm at it.

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.
