Watch app beta testing

Hi guys.
I've made watch app with Connect IQ.
Now I want another person (QA) to be able to install it and make a test.
How can I do that without publishing app ?

I was reading documentation. Found "Beta testing" section.
But it's says "URLs to the beta will not be visible outside of your account."
Meaning QA will no be able to see it ?
Any suggestions ?
Thanks
