How do I test a new app that has not been published against the shipping api?

Question

I have been given access to the new shipping api, when creating an app in partner section and subsequent editing of it details I can set it as a shipping app.

I can then add a shipping rate provider in the test shop (same partner account) but can only see USPS, Canada post, Fedex etc..and can not see the app. I imagine this is because the test app has not been published. But I do not want to publish the test app, and a requirement to publish an app before it can be added as a shipping provider would sort of hinder developement and testing ;-)

I have tried visiting http://your-store.myshopify.com/admin/api/auth?api_key=YOUR_API_KEY but I can't see how that will add my test app as a shipping rate provider in the shipping preferences of the test app.

In fact I gave up on using http://your-store.myshopify.com/admin/api/auth?api_key=YOUR_API_KEY and moved over to user Oauth2 (I couldn't seem to get legacy auth examples working.)

I can register the app via OAuth2 however the option for this shipping app does not appear in the "Carrier calculated shipping rates"

Now I am really stumped.

1. Make sure that the app you created has checked the “this is a shipping app” box.
2. Visit http://YOUR-STORE.myshopify.com/admin/api/auth?api_key=YOUR_API_KEY
3. Visit https://YOUR-STORE.myshopify.com/admin/shipping and the shipping service your app exposes should be available as a carrier-calculated shipping rate. (Hit that button at the top of the page if you haven’t added any yet.)
