pipes doesn't care about error codes and ignore them thus we should not use them in tests.
As an easy alternative, I am using a tmp file to write from git command so we can test the exit code.

Please be careful about the length of your lines in your
commit message. vim should auto-wrap as you write.

Oops, I mostly use Nano, I think it's time to use vim. I will take care of it.

There are also some grammar issues, so here is an update
to what you wrote:

  Git output so we can test the exit code.

Thanks for pointing this out. I will update it. I am a non-native
English speaker, and looking to improve my command in language with
time :)

Split each part of the &&-chain across lines, like this:

+               find .git/worktrees -print >tmp &&
+               sort tmp >expected &&

quoted

              git -C ../linked-worktree init &&
              test_cmp expected-exclude .git/info/exclude &&
              test_cmp expected-config .git/config &&
-             find .git/worktrees -print | sort >actual &&
+             find .git/worktrees -print >tmp && sort tmp >actual &&

Here, too.

I could make the same comments on patch 2, but I think you
have enough info to go on.

Sure, I get it! I will consider all these suggestions in v2.

Thanks,
