SALESFORCE-PD1 Process Automation And Logic Practice Question
A developer implements a Queueable class that makes an external REST callout. The developer needs to test this class using Test.startTest() and Test.stopTest(). What is required for the callout to succeed in the test method?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement the HttpCalloutMock interface and assign it using Test.setMock()
Callouts are not allowed in test methods unless mocked. The test must implement the HttpCalloutMock interface to simulate the response.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the remote site setting active in the test context.
Why it's wrong here
Remote site settings are bypassed during tests; mocking is still required for the code to execute successfully.
- ✓
Implement the HttpCalloutMock interface and assign it using Test.setMock()
Why this is correct
Salesforce requires callouts in tests to be mocked using Test.setMock().
- ✗
Use the Database.AllowsCallouts interface on the test class.
Why it's wrong here
Test methods cannot implement Database.AllowsCallouts; mocking is mandatory.
- ✗
Wrap the callout in a try-catch block to bypass test restrictions.
Why it's wrong here
A try-catch block does not bypass the platform restriction preventing live callouts in tests.
