Do we need this?

We do. I think there are ways to improve the terminology, but technically the arrow_test_dep becomes a disabler only if needs_testing is false. It is possible for needs_tests to be false while needs_testing is true. Without this extra condition these tests would build when -Dtests=false and -Dtesting=true

I do wonder if it wouldn't be better to have an arrow_test_dep and separately an arrow_testing_dep

If we need this here, we need it for test('arrow-utility-test', exc) too?

It seems that we don't need both arrow_test_dep and arrow_testing_dep. Can we use this instead?

if needs_tests
    arrow_test_dep = declare_dependency(
        link_with: [arrow_test_lib],
        dependencies: [arrow_dep, filesystem_dep, gmock_dep, gtest_main_dep],
    )
else
    arrow_test_dep = disabler()
endif

Nice catch on the arrow-utility-test - I can do that.

With respect to the if needs_tests, it depends how much we want to adhere to what CMake has in place. In fact, we used to use that same condition, but I had to change it from if needs_tests to if needs_testing in the benchmarks PR.

https://github.com/apache/arrow/pull/45793/files

Unless I am misreading the CMake configuration (which is certainly possible) it seems like it is possible to disable tests but turn the benchmarks on. In such a case, you would still need the current arrow_test_dep dependency to build benchmarks; the change you are proposing would add a dependency between the test suite and benchmark suite

Can we use separated dependency for benchmarks something like the following?

if needs_tests
    arrow_test_dep = declare_dependency(
        link_with: [arrow_test_lib],
        dependencies: [arrow_dep, filesystem_dep, gmock_dep, gtest_main_dep],
    )
else
    arrow_test_dep = disabler()
endif

if needs_benchmarks
  arrow_benchmark_dep = declare_dependency(
        dependencies: [benchmark_dep, arrow_test_dep],
    )
else
  arrow_benchmark_dep = disabler()
end

Yes we can. Nice idea!

foreach key, val : util_tests
exc = executable(
key,
sources: val['sources'],
dependencies: [arrow_test_dep, val.get('dependencies', [])],

Do we need gtest_main_dep here?

arrow_test_dep already provides gtest_main_dep transitively

Ah, arrow_test_dep doesn't link to only libarrow_testing.so.

Then can we remove filesystem_dep from arrow-crc32-test dependencies?

Ah nice catch - yea we can do that for now
