Commit Message

Ævar Arnfjörð Bjarmason July 28, 2022, 4:16 p.m. UTC 
Create a new "test-tool submodule" and move the "is-active" subcommand
over to it. It was added in 5c2bd8b77ae (submodule--helper: add
is-active subcommand, 2017-03-16), since
a452128a36c (submodule--helper: introduce add-config subcommand,
2021-08-06) it hasn't been used by git-submodule.sh.

Since we're creating a command dispatch similar to test-tool.c itself
let's split out the "struct test_cmd" into a new test-tool-utils.h,
which both this new code and test-tool.c itself can use.

I'm underqualified to comment on structure of test-tool, so I won't
comment on that, but it makes sense to convert code that is only used in
tests into test helpers.

That said, don't we only use "git submodule--helper is-active" inside
the tests for "git submodule--helper is-active"? If so, I'd think the
right thing to do is to just get rid of the code altogether.

The exception IMO, is if we think that we want a kind of "unit test"
that checks our logic for determining if a submodule is active. I don't
really think that's necessary, but if so, we probably want to update the
description of t7413 to describe that intent.
