NEW QUESTION # 115
A developer created a trigger on the Account object and wants to test if the trigger is properly bulkified. The developer team decided that the trigger should be tested with 200 account records with unique names.
What two things should be done to create the test data within the unit test with the least amount of code?
Choose 2 answers
  • A. Use the @isTest (isParallel=true) annotation in the test class.
  • B. Create a static resource containing test data.
  • C. Use Test.loadData to populate data in your test methods.
  • D. Use the @isTest (seeAllData=true) annotation in the test class.
Answer: B,C
Explanation:
To test the trigger with 200 account records with unique names using the least amount of code:
Option A: Use Test.loadData to populate data in your test methods.
Reference:
"Test.loadData lets you populate test records by loading the contents of a CSV file into sObjects for use in test methods."
- Apex Developer Guide: Using Test.loadData
Option B: Create a static resource containing test data.
"Create a static resource that contains the .csv file for the records you want to load."
- Apex Developer Guide: Loading Test Data from Static Resources
Why Other Options Are Incorrect:
Option C: The @isTest(isParallel=true) annotation is used to run tests in parallel but does not help in creating test data.
Option D: Using @isTest(seeAllData=true) allows access to existing org data, which is not recommended and does not help create unique test data with minimal code.

NEW QUESTION # 116
A developer is asked to write helper methods that create test data for unit tests.

What should be changed in the TestUtils class so that its methods are only usable by unit test methods?
  • A. Change public to private on line 01.
  • B. Add @istest above line 01.
  • C. Remove static from line 03.
  • D. @isTest above line 03.
Answer: B
Explanation:
To ensure that the TestUtils class and its methods are only accessible by unit test methods, the class must be annotated with the @isTest annotation. This annotation limits the scope of the class and its methods to test contexts only.
Why @isTest?
Purpose of @isTest:
The @isTest annotation marks a class or method for use exclusively within test scenarios. It prevents the methods from being accidentally invoked in production code.
This ensures better test isolation and prevents misuse.
Static Test Data Methods:
Marking helper methods for test data creation as @isTest ensures they do not interfere with production code and are strictly for testing purposes.
Analysis of Options:
Option A: @isTest above line 03:
Incorrect. Applying @isTest only to the createAccount method would work, but the other methods in the class would still be accessible. This does not satisfy the requirement of restricting the entire class.
Option B: Add @isTest above line 01:
Correct. Annotating the class ensures all methods within the class are accessible only in the context of tests.
Option C: Change public to private on line 01:
Incorrect. Changing the class to private would cause a compilation error, as top-level classes in Salesforce cannot be declared private.
Option D: Remove static from line 03:
Incorrect. Removing static does not affect the test scope of the class or its methods. Static methods can still be invoked, and this does not restrict access to test contexts.
Correct Implementation:
The corrected code would look like this:
@isTest
public class TestUtils {
public static Account createAccount() {
Account acct = new Account();
// Set some fields on acct
return acct;
}
// Other methods...
}

    Request.addError {'Your request cannot be created at this time.'};
    }
  • B. Trigger RequestTrigger on Request (after insert) {
    RequestLogic.validateRecords {trigger.new};
    }
  • C. Trigger RequestTrigger on Request (before insert) {
    if (RequestLogic.isvalid{Request})
    Request.addError {'Your request cannot be created at this time.'};
    }
  • D. Trigger RequestTrigger on Request (before insert) {

    }
