Code:
$ ssh host1 'test -e /etc/resolv.conf' ; echo $?
0
$ ssh host1 'test -e /etc/resolv.confa' ; echo $?
1
$ ssh host1a 'test -e /etc/resolv.conf' ; echo $?
ssh: host1a: Name or service not known
255
$ ssh host1a 'test -e /etc/resolv.confa' ; echo $?
ssh: host1a: Name or service not known
255
$ ssh user@host2 'test -e /etc/resolv.conf' ; echo $?
ksh: test: argument expected
1
$ ssh user@host2 'test -f /etc/resolv.conf' ; echo $?
0
$ ssh user@host2 'test -f /etc/resolv.confa' ; echo $?
1

OpenSSH always passes back the return code of the command, your only problem might be if the command returns 255, since that would make it difficult to discern between an SSH error and an application error.

Maybe your hosts' test command doesn't know about the -e switch. Use -f instead (which doesn't check for existence but whether it's a file or not. Will fail on directories)

SSH-COPY-ID(1)						    BSD General Commands Manual 					    SSH-COPY-ID(1)

NAME
ssh-copy-id -- copy public keys to a remote host SYNOPSIS
ssh-copy-id [-lv] [-i keyfile] [-o option] [-p port] [user@]hostname DESCRIPTION
The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required). The following options are available: -i file Copy the public key contained in file. This option can be specified multiple times and can be combined with the -l option. If a private key is specified and a public key is found then the public key will be used. -l Copy the keys currently held by ssh-agent(1). This is the default if the -i option was not specified. -o ssh-option Pass this option directly to ssh(1). This option can be specified multiple times. -p port Connect to the specified port on the remote host instead of the default. -v Pass -v to ssh(1). The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name. EXIT STATUS
The ssh-copy-id utility exits 0 on success, and >0 if an error occurs. EXAMPLES
To send a specific key to multiple hosts: $ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3 HISTORY
The ssh-copy-id utility was written by Eitan Adler <eadler@FreeBSD.org> as a drop-in replacement for an existing utility included with OpenSSH. BSD
