It's in /usr/bin on Debian.
unicorn:~$ type -a test [
test is a shell builtin
test is /usr/bin/test
[ is a shell builtin
[ is /usr/bin/[
unicorn:~$ ls -ld /usr/bin/[ /usr/bin/test
-rwxr-xr-x 1 root root 60224 Sep 24 2020 '/usr/bin/['
-rwxr-xr-x 1 root root 56128 Sep 24 2020 /usr/bin/test
I'm a bit surprised they're not the same program. And also that they're
that large. And that different in size from each other.
The external versions of test and [ need to exist for POSIX conformance,
and also so that you can -exec them from find(1) or other similar
programs.
