You can set and test a prerequisite like this: test_set_prereq FOO test_have_prereq FOO && echo yes You can negate the test in the shell like this: ! test_have_prereq && echo no However, when you are using the automatic prerequisite checking in test_expect_*, there is no opportunity to use the shell negation. This patch introduces the syntax "!FOO" to indicate that the test should only run if a prerequisite is not meant. One alternative is to set an explicit negative prerequisite, like: if system_has_foo; then test_set_prereq FOO else test_set_prereq NO_FOO fi However, this doesn't work for lazy prerequisites, which associate a single test with a single name. We could teach the lazy prereq evaluator to set both forms, but the code change ends up quite similar to this one (because we still need to convert NO_FOO into FOO to find the correct lazy script).

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.
