From: Amisha Chhajed Date: Sun, 25 Jan 2026 20:14:59 GMT Subject: [PATCH 1/2] u-string-list: add unit tests for string-list methods Message-ID: <20260125201500.63904-1-amishhhaaaa@gmail.com> In-Reply-To: <20260122171523.94234-1-amishhhaaaa@gmail.com> 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() Signed-off-by: Amisha Chhajed --- t/unit-tests/u-string-list.c | 197 +++++++++++++++++++++++++++++++++++ 1 file changed, 197 insertions(+) diff --git a/t/unit-tests/u-string-list.c b/t/unit-tests/u-string-list.c index a2457d7b1e..6b4b858330 100644 --- a/t/unit-tests/u-string-list.c +++ b/t/unit-tests/u-string-list.c @@ -243,6 +243,133 @@ void test_string_list__filter(void) t_string_list_clear(&list, 0);
