Message-ID: <20260326112149.53050-1-zakariyahali100@gmail.com>

```
Replace bare 'test -f/-d' and 'test ! -h ... && test -f/-d'
assertions with their dedicated test_path_is_* helpers.

These helpers are better than the previous 'test' commands
because they produce clearer diagnostic output on failure.
For example, instead of a bare exit code, the helper outputs
'File path0 doesn't exist', which makes test failures
significantly easier to debug.

The replacements are:
- 'test -f' -> 'test_path_is_file'
- 'test -d' -> 'test_path_is_dir'
- 'test ! -h && test -f' -> 'test_path_is_file_not_symlink'
- 'test ! -h && test -d' -> 'test_path_is_dir_not_symlink'

This should be sent as v2 in reply to your previous v1, not a new thread.
read Documentation/SubmittingPatches and
Documentation/MyFirstContribution as I mentioned in your v1.

The commit message is better now, but it's very verbose. The list
about what helpers have you changed can be looked at by any reviewer
with git log -p and the example only describes one helper, you should
be able to make it more general with something like: reports loudly
what expectation wasn't met, therefore making debugging easier.

Code looks OK.
