+       git switch -c dev &&

If someone adds a new test after this test, then that new test will
run in the "dev" branch, which might be unexpected or undesirable. It
often is a good idea to ensure that tests do certain types of cleanup
to avoid breaking subsequent tests. Here, it would be a good idea to
ensure that the test switches back to the original branch when it
finishes (regardless of whether it finishes successfully or
unsuccessfully).

    git switch -c dev &&
    test_when_finished "git switch master" &&

Or you could use `git switch -` if you don't want to hard-code the
name "master" in the test (since there has been effort lately to
remove that name from tests.

I have little confuse about I can use` test_when_finished "git switch master" `,
but I can't use` test_when_finished "git switch -" `,
why？

You may use either one. I presented both as alternative approaches.

I am sensing a bit of miscommunication here.  You sound like you
still believe either would work OK, but to me, it sounds like that
the author claims the one of them does not work for him/her.

I do not think the test framework itself mucks with the reflog to
make switching to "-" (or "@{-1}") break, so I find it implausible
that "switch -" form not to work, and unlike your "either is OK", I
have a moderately strong preference to use the "go back to the
previous one, whatever it is called" form.

Thanks.
