Next, we define three arguments: country, stat, and expected, which we will use within our test function. Then, we should create a list with Tuple entries. Each Tuple entry on lines 30 through 32 defines one of the three given test scenarios. We must make sure to update the decorators to find attributes as our function arguments. This is done on line 34. Now we must move on to change other contents of this function.
