Subject: t-reftable-record: add comparison tests for index records
X-Git-Tag: v2.46.0-rc1~22^2~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=85ca39e79b3fc3baed8ae218ac52af953121977a;p=thirdparty%2Fgit.git

t-reftable-record: add comparison tests for index records

In the current testing setup for index records, the comparison
functions for index records, reftable_index_record_cmp() and
reftable_index_record_equal() are left untested.

Add tests for the same by using the wrapper functions
reftable_record_cmp() and reftable_record_equal() for
reftable_index_record_cmp() and reftable_index_record_equal()
respectively.
