title: Google Play In-App Billing - Testing GetPurchases - static responses?
body: <p>I am just getting started with Google Play In-App purchases. I want to get everything working with Google Play's static responses before creating test products.</p>
  
  <p>I know that I can test making purchases using their reserved product IDs, such as android.test.purchased.</p>
  
  <p>But, the next step is verifying the user's past purchases, using GetPurchases(). How can I test that using static responses?</p>
  
  <p>If I "purchase" the "android.test.purchased" product, then later call GetPurchases(), will it return that item?</p>
  
  <ul>
  <li><p>If not, what is the correct way to get a <strong>static</strong> response from
  GetPurchases() that returns a result showing that a product is indeed purchased?</p></li>
  <li><p>If so, what do I need to do to "reset" it, so that it shows the special reserved product as unpurchased later for subsequent tests?</p></li>
  </ul>
