2025-03-04t/unit-tests: convert trailer test to use clarSeyi Kuforiji1-317/+0
Adapt trailer test file to use clar testing framework by using clar assertions where necessary. Split test into individual test functions for clarity and maintainability. Each test case now has its own function, making it easier to isolate failures and improve test readability.

2024-12-06global: mark code units that generate warnings with `-Wsign-compare`Patrick Steinhardt1-0/+2
Mark code units that generate warnings with `-Wsign-compare`. This allows for a structured approach to get rid of all such warnings over time in a way that can be easily measured. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-08-17unit-tests: ignore unused argc/argvJeff King1-1/+1
All of the unit test programs have their own cmd_main() function, but none of them actually look at the argc/argv that is passed in. In the long run we may want them to handle options for the test harness. But we'd probably do that with a shared harness cmd_main(), dispatching to the individual tests. In the meantime, let's annotate the unused parameters to avoid triggering -Wunused-parameter. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-05-02trailer unit tests: inspect iterator contentsLinus Arver1-13/+148
Previously we only checked whether we would iterate a certain (expected) number of times. Also check the parsed "raw", "key" and "val" fields during each iteration.

2024-05-02trailer: teach iterator about non-trailer linesLinus Arver1-5/+11
Previously the iterator did not iterate over non-trailer lines. This was somewhat unfortunate, because trailer blocks could have non-trailer lines in them since 146245063e (trailer: allow non-trailers in trailer block, 2016-10-21), which was before the iterator was created in f0939a0eb1 (trailer: add interface for iterating over commit trailers, 2020-09-27). So if trailer API users wanted to iterate over all lines in a trailer block (including non-trailer lines), they could not use the iterator and were forced to use the lower-level trailer_info struct directly (which provides a raw string array that includes all lines in the trailer block). Change the iterator's behavior so that we also iterate over non-trailer lines, instead of skipping over them. The new "raw" member of the iterator allows API users to access previously inaccessible non-trailer lines. Reword the variable "trailer" to just "line" because this variable can now hold both trailer lines _and_ non-trailer lines. The new "raw" member is important because anyone currently not using the iterator is using trailer_info's raw string array directly to access lines to check what the combined key + value looks like. If we didn't provide a "raw" member here, iterator users would have to re-construct the unparsed line by concatenating the key and value back together again Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-05-02trailer: add unit tests for trailer iteratorLinus Arver1-0/+174
Test the number of trailers found by the iterator (to be more precise, the parsing mechanism which the iterator just walks over) when given some arbitrary log message. We test the iterator because it is a public interface function exposed by the trailer API (we generally don't want to test internal implementation details which are, unlike the API, subject to drastic changes).
