 Amazing, you just made a surrogate key! You can just move on to the next data model, right? No!! It’s  critically important to test your surrogate keys for uniqueness and non-null values to ensure that the correct fields were chosen to create the surrogate key.
 
-In order to test for null and unique values you can utilize code-based tests like [dbt tests](/docs/build/data-tests), that can check fields for nullness and uniqueness. You can additionally utilize simple SQL queries or unit tests to check if surrogate key count and non-nullness is correct.
