Re: [PATCH v3 1/2] u-string-list: add unit tests for string-list methods

>
> Unit tests in u-string-list.c does not cover several methods
> in string-list, this gap in coverage makes it difficult to
> ensure no regressions are introduced in future changes.
>
> Add unit tests for the following methods to enhance coverage:
> string_list_remove_empty_items()
> unsorted_string_list_has_string()
> unsorted_string_list_delete_item()
> string_list_has_string()
> string_list_insert()
> string_list_sort()
> string_list_remove()
