Test script missing from Invites 1.0.8

I just downloaded Invites v. 1.0.8 and the install file indicates:

If you are not sure if your server supports cURL you may use the test script included with this package. Just simply upload curl-test.php to your PHP enabled server.

The downloaded archive (1815246010_invite-1.0.8) however, only includes the following files:

  • changelog.txt
  • install.txt
  • invite.php
  • license.txt
  • support.txt

The changelog also indicates 1.5+ compatibility as of 05/05/2008, while download page indicates 2.7.1 compatibility. Is this plugin current and where can I get the script?
