Match the style to more modern test scripts, namely: - Prefer tabs for indentation. - The first line of each test has prereq, title and opening sq for the script body. - Move cleanup or initialization of data used by a test inside the test itself. - Put a newline before the closing sq for each test. - Don't conclude the test descriptions with a full stop. - Prefer 'test_line_count = COUNT FILE' over 'test $(wc -l <FILE) = COUNT' - Prefer 'test_line_count = 0 FILE' over 'cmp -s /dev/null FILE' - Use '<<-EOF' style for here documents, so that they can be indented as well. Bot don't do that in case the resulting lines would be too long. Also when there is no $variable_substitution in the body of a here document, quote \EOF. - Don't redirect the output of commands to /dev/null unconditionally, the git testing framework should already take care of handling test verbosity transparently and uniformly.

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.
