LGTM, thanks! This is a nice cleanup since it makes all of our tests use the same conventions.

You're missing an include of assert_macros.h here.

Same here, and probably elsewhere.

Thanks for the review.

Agreed, the tests still worked due to filesystem_test_helper.h including this file.

libcxx/test/std/input.output/filesystems/class.directory_entry/directory_entry.obs/hard_link_count.pass.cpp
172

I had that already done locally.

Due to the changes in the parent patch I've given the patch another CI run to make sure everything still works.

Avoid std::forward to avoid including the utility header.
