 ### Unit Tests
 
 To run the Mobile Buy SDK integration tests against an actual shop, you will need a Shopify shop that is publicly accessible (not password protected). Please note that the integration tests **will create an order** on that shop. This is to validate that the SDK works properly with Shopify.  Modify the **test_shop_data.json** file to contain your shop's credentials and the required product IDs, gift cards, and discounts as necessary.
 
-If the credentials in the **test_shop_data.json** are empty, running the integration tests will use using mocked respoonses.  The mocked responses are defined in **mocked_responses.json**.  Do not check in credentials in this file.
