import statements fail - deployment

Question

I'm a Puppet newbie. I'm trying to setup a chef-style deployment environment. I have a puppet-master server set up, and I'd like to be able to configure/deploy to two nodes that I set up simultaneously.
What I'm expecting with my puppet setup right now is for my two servers (called img01 and img02) to automatically create a file called /tmp/test_file.txt.
I'm not even sure how to really "load in" a manifest. I just assumed that anything in site.pp would automatically get loaded, but that doesn't seem to be the case. When I run "puppet apply /etc/puppet/manifests/site.pp", I get the following:
Error: Could not parse for environment production: No file(s) found for import of 'test' at /etc/puppet/manifests/site.pp:3 on node puppet.lgwp.com
Error: Could not parse for environment production: No file(s) found for import of 'test' at /etc/puppet/manifests/site.pp:3 on node puppet.lgwp.com
This is what my manifest setup looks like right now:
Cert list on the puppet-master server:
+ "img01.lgwp.com.com" (SHA256) (omitted)
+ "img02.lgwp.com" (SHA256) (omitted)
+ "puppet.lgwp.com" (SHA256) (omitted) (alt names: "DNS:puppet.lgwp.com")
/etc/puppet/manifest/site.pp:
import "test"
import "nodes"
Exec { path => "/usr/bin:/usr/sbin/:/bin:/sbin" }
/etc/puppet/manifest/nodes.pp:
import "test"
node "imageserver" {
include "tempfile"
}
node 'img01.lgwp.com' inherits imageserver {
}
node 'img02.lgwp.com' inherits imageserver {
}
/etc/puppet/modules/test/manifests/test.pp:
class test {
package { test: ensure => latest }
file { "test_file":
path => '/tmp/test_file.txt',
ensure => present,
mode => 0755,
content => 'hola world',
source => "puppet:///modules/test/test_file",
require => Package["test"],
}
}

Don't use import. Just don't.
Remove the existing import statements and change the manifest setting in your puppet.conf to include all files in /etc/puppet/manifests.
[main]
manifest=/etc/puppet/manifests/
include tempfile makes no sense either, unless you have a tempfile module. Try
include test
Other classes in the test module should be named test::something and can also just be included. Puppet locates the manifests in the according modules. There is literally no need to use import anymore.
