An Apex class does not achieve expected code coverage. The testSetup method explicitly calls a method in the Apex class.
How can the developer generate the code coverage?

• Verify the user has permissions passing a user into System.runAs().

• Call the Apex class method from a testMethod instead of the testSetup method.

• Add @testVisible to the method in the class the developer is testing.

• Use system.assert() in testSetup to verify the values are being returned.

Users upload .csv file in an external system to create account and contact records in Salesforce. Up to 200 records can be created at a time. The users need to wait for a response from Salesforce in the external system, but the data does not need to synchronize between the two systems.

• REST API request using composite/batch/

• REST API request using composite/tree/

• Apex web services

• Bulk API 2.0

Consider the controller code above that is called from a Lightning component and returns data wrapped in a class.

The developer verified that the Queries return a single record each and there is error handing in the Lightning component, but the component is not getting anything back when calling the controller getSomeData().

What is wrong?

• Instances of Apex classes such as MyDataWrapper cannot be returned to a Lightning component.

• The member's Name and Option should not have getter and setter.

• The member's Name and Option of the class MyDataWrapper should be annotated with @AuraEnabled too.

• The member's Name and Option should not be declared public.
