How to test installation on non dev domain

I'm developing a google apps marketplace app. There's the Test install flow button on the dashboard, but I'd like to test installation on another domain of ours - to see that permissions, token etc. work as expected. Is there a way to install an (it's non published yet) on a domain which is not related to development?

Solution

Found a solution, this was surprisingly straightforward, but it worked for me:

Open two browser windows, one for your dev account (dev.com) and one for the domain you wish to test on (test.com)

In you dev account, go to the dashboard and click the Test installation flow button
In the popup that you get, go to the address bar and copy the link
Now go to the browser with your test.com domain, and enter this address
You'll be asked to login, and then you'll get the consent screen
You should now see the app in your test.com`s marketplace apps list
