PD1 Testing, Debugging & Deployment 2 — Questions and Answers
Question 1: Which System.assert method should you use when you want to verify that two values are equal in an Apex test?
- System.assert(val1, val2)
- System.assertEquals(val1, val2) (Correct answer)
- System.assertNotEquals(val1, val2)
- System.assertMatch(val1, val2)
Correct answer: System.assertEquals(val1, val2)
System.assertEquals(expected, actual) compares two values and fails the test if they are not equal.
Question 2: What is the minimum test code coverage percentage required to deploy Apex to a Salesforce production org?
- 50%
- 60%
- 75% (Correct answer)
- 100%
Correct answer: 75%
Salesforce requires at least 75% aggregate test code coverage across all Apex code to deploy to production.
Question 3: Which class is used to set mock responses for callouts in Apex tests?
- Test.setMock() (Correct answer)
- Callout.setMock()
- HttpMock.set()
- Test.setCalloutMock()
Correct answer: Test.setMock()
Test.setMock() registers a mock implementation that intercepts HTTP callouts during test execution.
Question 4: What happens when you run a Salesforce deployment with the 'checkOnly' flag set to true?
- The deployment is committed to production
- A validation is performed without saving components (Correct answer)
- Only metadata is deployed, not Apex
- Code coverage is skipped
Correct answer: A validation is performed without saving components
A checkOnly deployment validates all components and runs tests without persisting any changes to the org.
Question 5: Which annotation marks an Apex method as a test setup method that runs once before any test methods in the class?
- @testSetup (Correct answer)
- @isTest(setup=true)
- @beforeAll
- @TestFixture
Correct answer: @testSetup
@testSetup creates a single set of test data that is rolled back and re-created for each test method.
Question 6: What tool in Salesforce allows developers to view debug logs filtered by user or by log category?
- Developer Console (Correct answer)
- Workbench
- Apex Explorer
- Schema Builder
Correct answer: Developer Console
The Developer Console provides a log panel where you can filter, open, and analyze debug logs by user and category.
Question 7: In a sandbox-to-production deployment, which of the following is NOT deployed by the Change Set process?
- Apex classes
- Custom objects
- User records (Correct answer)
- Validation rules
Correct answer: User records
Change Sets deploy metadata (configuration and code) but do not migrate data records such as user records.
