SALESFORCE-PD1 Testing Debugging And Deployment — 30 Questions

Question 1

A developer wants to ensure that test methods in a managed package upgrade test all triggers and classes, and needs to bypass existing organization test data to use only packaged data. Which annotation parameter should be used?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

@testSetup. The @isTest(SeeAllData=true) annotation allows test methods to access organization data, but by default tests do not see org data. To ensure standard test isolation or handle specific packaged test visibility, developers manage data appropriately. However, the exact mechanism to ignore org data when strict isolation is desired is the default @isTest behavior. Wait, let's frame it as testing legacy code: when using @isTest(SeeAllData=true), tests can access org data. If a developer needs to insert test data without using setup objects, @TestSetup is used. Let's make the question about @TestSetup efficiency.

Answer

@future(isTest=true)

Answer

@testVisible

Answer

@isTest(seeAllData=true)

Question 2

A developer needs to write a unit test that verifies user permissions and accessibility before executing business logic. Which TWO methods or classes are valid for simulating different user contexts in Apex tests? (Choose two.)

Accepted Answer

Test.runAs(). Test.runAs() allows running tests as a specific user. UserInfo class methods can inspect the running user.

Answer

Database.setSessionUser()

Answer

Test.startTest() with a user profile parameter

Answer

UserInfo.setUserId()

Answer

System.runAs()

Question 3

Which annotation allows a private method in an Apex class to be visible to unit test classes for assertion purposes?

Accepted Answer

@TestVisible. @TestVisible allows access to private or protected members within test classes.

Answer

@RemoteAction

Answer

@AuraEnabled

Question 4

A developer wants to test an asynchronous future method. Where must the developer place the asynchronous code execution so that it runs synchronously and within the test context?

Accepted Answer

Between Test.startTest() and Test.stopTest(). Test.startTest() and Test.stopTest() bracket the code block where asynchronous processes like future methods, batch jobs, and queueables are forced to execute synchronously.

Answer

Inside a System.runAs() block

Answer

Within a try-catch block

Answer

Inside a Database.executeBatch block

Question 5

A developer is analyzing a debug log and notices that it is truncated because it exceeded the maximum file size limit. Which action should the developer take to capture only the relevant Apex code execution details without exceeding the limit?

Accepted Answer

Adjust the Trace Flag log levels to reduce verbosity for unnecessary categories like Database and Workflow.. Refining log categories and levels ensures only necessary debug statements are recorded, preventing truncation.

Answer

Increase the maximum log file size in company profile settings.

Answer

Disable all validation rules in the org temporarily.

Answer

Switch the debug log perspective to 'Development Harvester'.

Question 6

A developer receives a System.LimitException: Too many SOQL queries: 101 when running a complex unit test. The test class inserts a large volume of test records that inadvertently cause a trigger to execute multiple queries inside a loop. What is the most effective way to reset the governor limits specifically for the code being tested?

Accepted Answer

Wrap the test assertion code between Test.startTest() and Test.stopTest().. Test.startTest() resets all governor limits for the code executed immediately following it, up until Test.stopTest().

Answer

Mark the test method with @isTest(SeeAllData=true).

Answer

Wrap the trigger logic in a Database.setSavepoint() block.

Answer

Use Limits.getLimitQueries() inside the test method.

Question 7

A developer is writing a unit test that executes under a specific user context to verify sharing rules. Which method should the developer use to specify the user for the subsequent test operations?

Accepted Answer

System.runAs(). System.runAs() enables developers to run test methods under a specific user context to verify record-level security and sharing rules.

Answer

UserInfo.setUserId()

Answer

Database.setSavepoint()

Answer

Test.setCurrentUser()

Question 8

A developer wants to view real-time debug log streaming in their local environment using the Salesforce CLI. Which command should the developer execute?

Accepted Answer

sf apex log tail. The sf apex tail log command streams debug logs to the terminal in real time.

Answer

sf apex run test

Answer

sf project deploy start

Answer

sf org display

Question 9

A developer is writing a test method that performs a callout to an external REST service. Which interface must the developer implement to provide mock responses during the unit test execution?

Accepted Answer

HttpCalloutMock. HttpCalloutMock is the interface implemented to supply a mock HTTP response during test context when callouts are made.

Answer

InstallHandler

Answer

Schedulable

Answer

Database.Batchable

Question 10

A developer has written a test method that requires a large volume of test data to be set up. To avoid writing duplicate data setup code across multiple test methods in the same class, which annotation should the developer use?

Accepted Answer

@TestSetup. The @TestVisible annotation is incorrect for data setup. The @TestSetup annotation executes once per test class and creates data for all test methods in that class.

Answer

@isTest(SeeAllData=true)

Answer

@TestVisible

Answer

@Future

Question 11

A developer needs to write a unit test to verify that a trigger correctly inserts related Task records when a custom object record is created. Which annotation should the developer place on the test class method to ensure it runs correctly and can access existing org data if needed?

Accepted Answer

@isTest. The @isTest annotation identifies a method or class as containing unit tests. Using @isTest(SeeAllData=true) is sometimes required when legacy data must be accessed, though best practice is to create test data locally.

Answer

@ReadOnly

Answer

@TestVisible

Answer

@TestSetup

Question 12

A developer is using Salesforce CLI to create a temporary environment for feature development and testing that includes all source code and shape settings. Which CLI command should the developer use to create this temporary environment?

Accepted Answer

sf org create scratch. sf org create scratch creates a scratch org based on a definition file.

Answer

sf org login web

Answer

sf org create sandbox

Answer

sf project retrieve start

Question 13

A developer is deploying a profile and custom fields using an Unmanaged Change Set. Upon deployment, some custom field permissions fail to apply correctly in production. What is the most likely cause of this behavior?

Accepted Answer

Field-level security settings on profiles are sometimes omitted or overridden if the target profile already exists and has conflicting security configurations.. Profiles and permission sets in change sets require careful component selection, and field-level security is often best handled via permission sets or post-deployment steps.

Answer

Unmanaged change sets require manual XML editing prior to upload.

Answer

Change sets do not support the deployment of custom fields under any circumstances.

Answer

Profiles cannot be included in outbound change sets.

Question 14

A developer is preparing to deploy metadata changes from a sandbox to a production org using Outbound Change Sets. Where must the administrator or developer establish the connection between the two organizations?

Accepted Answer

Deployment Settings in the target org. Deployment connections for change sets must be authorized and configured in Deployment Settings in the target production org.

Answer

Connected Apps in the production org

Answer

Named Credentials in both orgs

Answer

Remote Site Settings in the source org

Question 15

A developer has written a Lightning Web Component and Apex controller, and wants to deploy only these specific metadata components to a production org using Salesforce CLI without relying on change sets. Which command is appropriate?

Accepted Answer

sf project deploy start. sf project deploy start deploys source files from a local project directory to a target org.

Answer

sf apex run

Answer

sf org open

Answer

sf project convert mdapi

Question 16

A developer needs to verify code coverage across an entire Apex organization before deploying code to production. What is the minimum overall Apex code coverage required by Salesforce for production deployment?

Accepted Answer

75%. Salesforce requires a minimum of 75% overall Apex code coverage for deployment to a production organization.

Answer

100%

Answer

50%

Answer

85%

Question 17

A developer runs unit tests in the Developer Console and notices that one test method fails when run as part of the entire test class, but passes successfully when run in isolation. What is the most likely cause of this issue?

Accepted Answer

Test data pollution caused by another test method modifying shared records without resetting state.. Test pollution occurs when test data modified or created by one test method is not properly cleaned up, affecting subsequent test methods.

Answer

The Developer Console caches old test results automatically.

Answer

The test class lacks the @isTest annotation.

Answer

Governor limits are permanently exhausted for the entire session.

Question 18

A developer is writing a unit test and needs to assert that a specific custom exception was thrown during invalid input processing. Which pattern should the developer use?

Accepted Answer

Wrap the target code in a try block, add Assert.fail('Expected exception') after the target code, and catch the exception.. Using try-catch blocks with System.assert or Assert.fail inside the try block ensures that if the exception is not thrown, the test fails.

Answer

Use Test.expectException() before calling the method.

Answer

Check Limits.getScriptStatements() after the method call.

Answer

Use System.assert(false, e.getMessage()) inside the catch block.

Question 19

A developer wants to inspect the code coverage of individual classes directly within the Salesforce Developer Console. Under which tab can the developer view this breakdown?

Accepted Answer

Tests tab. The Tests tab in the Developer Console displays test execution status, test results, and code coverage percentages by class.

Answer

Query Editor tab

Answer

DOM Inspector tab

Answer

Logs tab

Question 20

Which TWO actions occur automatically when Test.stopTest() is called in an Apex unit test? (Choose two.)

Accepted Answer

All asynchronous queued processes (future, batch, queueable) are run synchronously.. Test.stopTest() executes asynchronous jobs and processes pending communications.

Answer

The user session is automatically logged out.

Answer

All custom objects in the organization are deleted and recreated.

Answer

The database is permanently committed to production.
