Pre-publishing of plugins for group of testers before release

Sharing plugins with testers

I am looking for a way to securely share my plugin with a potential tester without incurring a charge. I was wondering if it is possible to create a one-time 100% discount coupon that would allow them to download and test the plugin. Alternatively, if there is another secure method Adobe recommends for sharing plugins with testers, I would appreciate your guidance. Thank you!
