[GSoC][PATCH v2 0/4] t: port reftable/basics_test.c to the unit testing

[Chandra Pratap]

In the recent codebase update (commit 8bf6fbd, 2023-12-09), a new unit
testing framework written entirely in C was introduced to the Git project
aimed at simplifying testing and reducing test run times.
Currently, tests for the reftable refs-backend are performed by a custom
testing framework defined by reftable/test_framework.{c, h}. Port
reftable/basics_test.c to the unit testing framework and improve upon
the ported test.

Changes in v2:
- Split up the second patch of the previous series into sub-patches

CI for v2: https://github.com/gitgitgadget/git/pull/1736

[GSoC][PATCH v2 1/4] t: move reftable/basics_test.c to the unit testing framework

[Chandra Pratap]

reftable/basics_test.c exercise the functions defined in
reftable/basics.{c, h}. Migrate reftable/basics_test.c to the
unit testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework.

Oh, so this test was even duplicated. It may make sense to point out
details like this in the commit message to prepare the reader. But
that's probably not worth a reroll.

Probably.  But if you are sending out another round anyway, then it
is a good opportunity to update the proposed log message.

put_be16() is a function defined in reftable/basics.{c, h} for which
there are no tests in the current setup. Add a test for the same and
improve the existing test-case for parse_names().

I'd split out this change into yet another commit. Also, you say that
the test case is being "improved", but without mentioning what the
improvement actually is.

Would it make sense to have separate tests for each of the variants
instead of one test for all of these? Might make things a bit easier to
follow.

The evolution of a patch series can be followed a bit easier if
subsequent versions are attached to the initial thread. You can do this
by passing e.g. `--in-reply-to=<message-id>` to git-format-patch(1),
where the message ID is the one of the cover letter of the first
version.

I'd also recommend to attach a range diff to your cover letter via the
`--range-diff=` parameter. This range diff helps the reviewer to spot
what has changed between your preceding version and this one.

[GSoC][PATCH v3 0/4] t: port reftable/basics_test.c to the unit testing

[Chandra Pratap]

In the recent codebase update (commit 8bf6fbd, 2023-12-09), a new unit
testing framework written entirely in C was introduced to the Git project
aimed at simplifying testing and reducing test run times.
Currently, tests for the reftable refs-backend are performed by a custom
testing framework defined by reftable/test_framework.{c, h}. Port
reftable/basics_test.c to the unit testing framework and improve upon
the ported test.

    -    t: add test for put_be16() and improve test-case for parse_names()
    +    t: improve the test-case for parse_names()

    -    put_be16() is a function defined in reftable/basics.{c, h} for which
    -    there are no tests in the current setup. Add a test for the same and
    -    improve the existing test-case for parse_names().
    +    In the existing test-case for parse_names(), the fact that empty
    +    lines should be ignored is not obvious because the empty line is
    +    immediately followed by end-of-string. This can be mistaken as the
    +    empty line getting replaced by NULL. Improve this by adding a
    +    non-empty line after the empty one to demonstrate the intended behavior.

[GSoC][PATCH v3 1/5] t: move reftable/basics_test.c to the unit testing framework

[Chandra Pratap]

reftable/basics_test.c exercise the functions defined in
reftable/basics.{c, h}. Migrate reftable/basics_test.c to the
unit testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework.

[GSoC][PATCH v3 5/5] t: improve the test-case for parse_names()

[Chandra Pratap]

In the existing test-case for parse_names(), the fact that empty
lines should be ignored is not obvious because the empty line is
immediately followed by end-of-string. This can be mistaken as the
empty line getting replaced by NULL. Improve this by adding a
non-empty line after the empty one to demonstrate the intended behavior.
