SALESFORCE-PD1 Testing Debugging And Deployment Practice Test 6 — 15 Questions

Question 1

A developer is writing a test for a method that performs a callout. How must the callout be handled?

Accepted Answer

Implement the HttpCalloutMock interface.. Apex tests cannot make real HTTP callouts, so the developer must implement the HttpCalloutMock interface and register it with Test.setMock() before the callout is invoked. This allows the test to return a fabricated HttpResponse, making the callout deterministic and avoiding the 'callout not allowed' runtime error.

Answer

Use the @future annotation.

Answer

Use Test.startTest().

Answer

The test will automatically fail.

Question 2

Which THREE actions are best practices when deploying Apex classes to production?

Accepted Answer

Run all tests in the destination organization.. Running tests, validating, and using version control are key deployment practices.

Answer

Avoid using change sets.

Answer

Directly edit classes in production.

Question 3

How can a developer inspect the state of a private variable within a class during unit testing?

Accepted Answer

Use the @TestVisible annotation.. The @TestVisible annotation allows a test method in the same class or a test class in the same namespace to access private or protected members of the annotated class without changing the member's visibility for production code. This preserves encapsulation in production while enabling white-box testing of internal state. It can be applied to private variables, methods, and inner classes.

Answer

Change the class to @isTest.

Answer

There is no way to inspect private variables.

Answer

Make the variable public.

Question 4

When using the Salesforce CLI to deploy, what is the 'check-only' flag used for?

Accepted Answer

To validate the metadata without saving it to the org.. It validates the deployment without committing changes to the target org.

Answer

To force the deployment despite test failures.

Answer

To skip the compilation check.

Answer

To run only the tests.

Question 5

Which approach is recommended to ensure test data is cleaned up?

Accepted Answer

The platform automatically rolls back data created in tests.. Salesforce automatically rolls back all data created during a test method (and during @testSetup) when the test completes, so no manual cleanup is required. This transactional isolation ensures tests do not pollute the org's data and do not need finally blocks or delete statements.

Answer

Use the Test.stopTest() method.

Answer

Delete the records manually in the finally block.

Answer

Use a @testSetup method for cleanup.

Question 6

A developer is receiving 'Too many SOQL queries' errors in a trigger. What is the most likely cause?

Accepted Answer

Executing SOQL inside a for loop.. Performing SOQL inside a loop is the primary cause of this error.

Answer

Using too many debug statements.

Answer

Not enough test coverage.

Answer

Using the wrong trigger event.

Question 7

Which TWO of the following are valid ways to trigger an Apex test run?

Accepted Answer

Apex Test Execution page in Setup.. Tests can be run from the Developer Console and from the Apex Test Execution page.

Answer

From the User record.

Answer

By editing an Apex class.

Answer

From a Workflow Rule.

Question 8

What happens if a test class has a method annotated with @testSetup that fails to insert data?

Accepted Answer

The entire test class fails to execute.. When a method annotated with @testSetup fails — for example, because a DML insert throws an exception — the entire test class is aborted and no test methods execute. The @testSetup method runs once before all test methods in the class, so its failure prevents the shared test data from being created and the platform marks the whole class as failed.

Answer

The test execution proceeds, but without data.

Answer

The platform ignores the @testSetup failure.

Answer

Only the first test method fails.

Question 9

Which THREE pieces of information are displayed in the Apex Test Execution page?

Accepted Answer

Execution Status.. The page shows class name, status, and duration.

Answer

Code Coverage Percentage.

Answer

User who initiated the test.

Question 10

What is the primary function of the 'Developer Console'?

Accepted Answer

It is a browser-based IDE for developing in Salesforce.. It is an integrated development environment for writing, debugging, and testing Apex.

Answer

It is used for deploying to production.

Answer

It is a tool for end-user reporting.

Answer

It is used for managing user permissions.

Question 11

A developer wants to log information specifically when a condition is met. Which method is most appropriate?

Accepted Answer

System.debug().. System.debug() is the Apex method used to write messages to the debug log, and it can be wrapped in an if-condition to log only when a specific condition is met. It supports log levels (ERROR, WARN, INFO, DEBUG, FINE, FINER, FINEST) that map to the DebugLevel configuration.

Answer

System.log().

Answer

Apex.debug().

Answer

Log.info().

Question 12

What happens if a developer creates a test method that does not contain any assertions?

Accepted Answer

The test passes if the code executes without errors.. The test will pass as long as the code runs without error, but it is not a valid test.

Answer

The test is skipped by the compiler.

Answer

The compiler issues a warning.

Answer

The test fails immediately.

Question 13

Why should a developer ensure that test classes have at least 75% coverage for production deployment?

Accepted Answer

It is a requirement set by the Salesforce platform.. Salesforce enforces a minimum of 75% Apex code coverage for all production deployments, except for certain metadata types. This requirement ensures that a substantial portion of the code is tested before it reaches production, reducing the risk of runtime errors.

Answer

It makes the code run faster.

Answer

It prevents bugs entirely.

Answer

It automatically generates the test classes.

Question 14

Which of the following describes the behavior of Test.stopTest()?

Accepted Answer

It forces all queued asynchronous jobs to complete.. Test.stopTest() forces all asynchronous jobs queued during the test — future methods, batch jobs, and queueable jobs — to execute synchronously before the method returns. This allows the test to make assertions on the results of asynchronous processing within the same test method.

Answer

It clears all variables created in the test.

Answer

It resets the debug logs.

Answer

It stops all further execution of the test class.

Question 15

Which THREE things can a developer do with the Salesforce CLI?

Accepted Answer

Query data from an org.. Option B is correct because the Salesforce CLI provides the `sf data query` (formerly `sfdx force:data:soql:query`) command, which lets a developer run SOQL queries against an org and retrieve records. Option D is correct because the CLI includes the `sf org create scratch` (formerly `sfdx force:org:create`) command, which provisions scratch orgs from a Dev Hub using a definition file or flags. Option E is correct because the CLI supports metadata deployment via `sf project deploy start` (formerly `sfdx force:source:deploy` or `force:mdapi:deploy`), pushing source or metadata components to an org. Option A is not valid because license type is an org-level setting managed through the Company Information page in Setup or via the appropriate licensing/contract process, not through the Salesforce CLI. Option C is not valid because user password resets are performed in Setup (Users) or via the System Administrator profile's reset action, not through a standard Salesforce CLI command.

Answer

Modify the Org's license type.

Answer

Update user passwords.
