[PATCH 2/2] t: improve upon reftable/basics_test.c in the unit testing framework
Enhance the new test for reftable/basics.{c, h} in the unit testing
framework. The enhancements include:
- Move tests for functions in reftable/basics.{c, h} from
reftable/record_test.c and reftable/stack_test.c to the new unit test.
- Add tests for functions that are not currently tested, like put_be16.
- Improve the test-cases for the already existing tests.Mentored-by: Patrick Steinhardt <ps@pks.im>
