SALESFORCE-PD1 Testing Debugging And Deployment Practice Test 2 — 15 Questions

Question 1

When deploying via Metadata API, what happens if a test class fails during the deployment?

Accepted Answer

The deployment fails and rolls back all changes.. When deploying via Metadata API, if 'runAllTests' is set to true (or if tests are required by the deployment settings), a test failure causes the entire deployment to fail and roll back. However, if tests are not required or not triggered, the deployment can succeed. The explanation should clarify that this behavior is dependent on the deployment configuration.

Answer

Only the failing test class is ignored.

Answer

The deployment succeeds but flags a warning.

Answer

The deployment continues but prevents Apex compilation.

Question 2

Which TWO of the following are valid ways to specify which tests to run in the Salesforce CLI?

Accepted Answer

sfdx force:apex:test:run -s. In the Salesforce CLI (sfdx force:apex:test:run), you can specify which tests to run using the -n (--tests) flag for specific test classes or methods, and the -s (--suites) flag to run test suites. The -c flag is used to enable code coverage rather than specifying which tests to run.

Answer

sfdx force:apex:test:run -c

Answer

sfdx force:apex:test:run -f

Answer

sfdx force:apex:test:run -u

Question 3

Why must you use Test.startTest() when testing asynchronous Apex code?

Accepted Answer

To ensure asynchronous processes complete within the test execution context.. Test.startTest() resets the governor limits for the code block that follows it. When Test.stopTest() is called, all asynchronous processes (such as @future, Queueable, or Batch Apex) queued between the start and stop methods are executed synchronously before the test continues. It does not 'ensure' they complete within the context; it forces their execution.

Answer

To increase the execution time allowed for tests.

Answer

To save the test data to the database immediately.

Answer

To bypass user permission checks.

Question 4

Which utility class is used to assert that code behaves as expected in Apex tests?

Accepted Answer

System.assertEquals().. Historically, System.assertEquals() (and related System methods) was used to assert conditions in Apex tests. (Note: Salesforce later introduced the Assert class, but System.assertEquals() remains valid and a classic exam staple).

Answer

Test.assert().

Answer

Test.verify().

Answer

Assert.verify().

Question 5

A developer needs to measure the performance of a SOQL query. Which log category and level should be used?

Accepted Answer

Profiling: FINEST.. To measure the performance and execution metrics of SOQL queries (such as execution time, rows returned, etc.), the Profiling log category should be set to INFO or higher. The Database category logs database events like query strings, but Profiling is specifically designed for performance metrics.

Answer

Database: INFO.

Answer

System: DEBUG.

Answer

Apex Code: INFO.

Question 6

A developer needs to test a feature that relies on the current time. Which method should be used to simulate time?

Accepted Answer

Test.setSystemTime().. In Salesforce Apex, Test.setSystemTime() allows developers to set system time within test methods to test time-dependent functionality. Therefore, C is the correct built-in method to simulate time in this context.

Answer

DateTime.now().

Answer

Design code to use a custom provider that can be injected.

Answer

System.now().

Question 7

Why might a deployment fail due to 'Apex classes do not have sufficient coverage'?

Accepted Answer

Aggregate coverage is below 75%.. The combined coverage across all classes must be at least 75%.

Answer

Test classes are not marked @isTest.

Answer

Individual class coverage is below 75%.

Answer

The test classes are too large.

Question 8

What is the primary constraint on using @testSetup?

Accepted Answer

It must be a void method.. In Salesforce Apex, a method annotated with @testSetup is used to insert test data once for all test methods in a class. The primary structural constraint on a @testSetup method is that it must be static and return no value (void).

Answer

It creates data that is isolated from the test methods.

Answer

It cannot interact with the database.

Answer

It can only be used once per project.

Question 9

When testing a class that depends on Custom Settings, what is the best practice?

Accepted Answer

Mock the custom settings using a wrapper class.. Salesforce unit tests cannot access organization-level or user-level Custom Settings created in production unless they are inserted as test data within the test context, or retrieved using methods like 'getOrgDefaults()' if specific conditions are met, but best practice is to insert test-specific Custom Setting records in the test setup (TestSetup). Mocking with a wrapper class (Option C) is not the standard or best practice for Salesforce custom settings, whereas creating them in the test method/setup (as described in the explanation) corresponds to using test data rather than mocking.

Answer

Ignore the custom settings in the test.

Answer

Hardcode the values into the test.

Answer

Use the production custom settings.

Question 10

How can you run tests for a specific namespace using the CLI?

Accepted Answer

Using the --namespace flag.. Without specifying the tool or technology, a question about CLI flags like `--namespace` is ambiguous and unverifiable.

Answer

Using the --package flag.

Answer

You cannot filter by namespace.

Answer

By running all tests.

Question 11

What is the maximum number of debug logs that can be stored per user?

Accepted Answer

50.. Salesforce allows a maximum of 20 debug logs to be stored per user. When the limit of 20 logs is reached, the oldest debug logs are automatically overwritten by newer ones.

Answer

1,000.

Answer

There is no limit on count, only total size.

Answer

100.

Question 12

A developer needs to reset the governor limits within a test method to verify functionality that processes large amounts of records. Which method should be used?

Accepted Answer

Test.startTest(). Test.startTest() and Test.stopTest() reset the governor limits for the code executed between them.

Answer

System.resetLimits()

Answer

Test.loadData()

Answer

Test.stopTest()

Question 13

Where can a developer view the generated debug logs for an Apex execution in the Salesforce UI?

Accepted Answer

Setup > Monitor > Debug Logs. In Salesforce Lightning Experience, Debug Logs are located by navigating to Setup > Environments > Logs > Debug Logs, or simply by typing 'Debug Logs' in the Quick Find box. The path 'Setup > Monitor > Debug Logs' is outdated and refers to older Salesforce navigation structures.

Answer

Setup > Deployment > Logs

Answer

Setup > Security > Audit Trail

Answer

Setup > Custom Code > Apex Settings

Question 14

A developer is writing a test class that requires several custom objects to be populated with data. What is the most efficient way to handle this across multiple test methods?

Accepted Answer

Use the @TestSetup annotation. The @TestSetup annotation defines a method that executes once before any test methods in the class, allowing for efficient data setup that is automatically rolled back after each test method completes. This is more efficient than recreating data in every test method.

Answer

Create a static method and call it at the start of every test method

Answer

Insert the data inside the constructor of the test class

Answer

Use the Test.loadData() method for all objects

Question 15

Which of the following is a limitation of Change Sets?

Accepted Answer

They can only be used between related orgs. Change Sets can only be used between Salesforce organizations that are associated with the same production organization (i.e., sibling or parent-child orgs that are 'related' via deployment connections). The original explanation discussed deployment direction (production to sandbox) rather than the organizational relationship requirement.

Answer

They cannot deploy Custom Objects

Answer

They are limited to 100 components

Answer

They require the CLI to be installed
