'Test Twitter and Facebook sharing on a development site

I want to see how sharing on my dev site is going to look on Facebook, Twitter, and Pinterest (I've added OG tags).

I know it's an oxymoron trying to test social sharing of a non-public site. But is there any way to do quality assurance of sharing before it is deployed to production? My dev URL is localhost but I do have a QA URL that is public but requires authentication.

I feel like I should be looking at this differently but I am not sure how. Must I wait until it's all live in production?
