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.
