This patchset seeks to add unit tests for the rest of the functions on the drm_rect.c. The test coverage report generated by the gcov[1] tool states that this set reaches 100% of coverage on the drm_rect.c file. This would be very good for future development on the file. Thanks for reviewing! Best regards, ~Arthur Grillo --- v1->v2: https://lore.kernel.org/all/20230322140701.69852-1-arthurgrillo@xxxxxxxxxx/ - Create parameterized tests for drm_rect_intersect(). - Use .16 binary fixed point values on the drm_rect_calc_hscale() and drm_rect_calc_vscale() tests. - Replace INT_MIN for 0 on the on the drm_rect_calc_hscale() and drm_rect_calc_vscale() tests. - Assign nonzero values to the width and height parameters of the drm_rect_rotate() and drm_rect_rotate_inv() tests. - Switch memcpy to a simple variable assignment on the drm_rect_rotate() and drm_rect_rotate_inv() tests. v2->v3: https://lore.kernel.org/all/20230327133848.5250-1-arthurgrillo@xxxxxxxxxx/ - Change "x" to lowercase on the drm_rect_intersect() cases. - Remove the option for no description on the drm_rect_intersect() cases. - Add a test for rects with zero height and width on the drm_rect_intersect(). - Switch to parameterized tests for drm_rect_calc_hscale() and drm_rect_calc_vscale(). - Add a test for a dst drm_rect with zero width for drm_rect_calc_hscale() and zero height for drm_rect_calc_vscale(). - Place an "-" on the drm_rect_rotate case names to match the userspace. - s/drm_rect_case_desc/drm_rect_rotate_case_desc/ - Improve the commit messages. --- [1]: https://gcc.gnu.org/onlinedocs/gcc/Gcov.html#Gcov --- Arthur Grillo (5): drm/tests: Add test cases for drm_rect_intersect() drm/tests: Add test cases for drm_rect_calc_hscale() drm/tests: Add test cases for drm_rect_calc_vscale() drm/tests: Add test cases for drm_rect_rotate() drm/test: Add test cases for drm_rect_rotate_inv() drivers/gpu/drm/tests/drm_rect_test.c | 362 ++++++++++++++++++++++++++ 1 file changed, 362 insertions(+) -- 2.39.2
