[PATCH v4 05/11] t-reftable-record: add comparison tests for obj records

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In the current testing setup for obj records, the comparison
functions for obj records, reftable_obj_record_cmp_void() and
reftable_obj_record_equal_void() 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_void() and reftable_index_record_equal_void()
respectively.
