Exam Certified Platform Developer II topic 1 question 339 discussion

C is correct You can't delete real records even during testing

I tested it. B is correct. The actual accounts will not be deleted but after delete operation in the test class it will return size as 0

it will not throw any error. the final assert succeeds.

D In the context of the test class, test accounts will hold 6 records containing the word "test." Five of them will come from the seeAllData = true context and one of them will come from the insert. Because it is a test class, any DML is not committed to the database, therefore to actually reference a deletion for assertion, you will have to create a new variable to hold the deletion. Please see the code below for reference. // Delete records delete recordsToDelete; // After the delete operation, you can assert that the records are deleted List<Custom_Object__c> deletedRecords = [SELECT Id FROM Custom_Object__c WHERE Id IN :recordsToDelete]; // Verify that the records are no longer present in the database System.assertEquals(0, deletedRecords.size(), 'Records should be deleted'); }
