NEW QUESTION # 189
An Apex class does not achieve expected code coverage. The testsetup method explicitly calls a method In the Apex class..
How can the developer generate the code coverage?
Answer: D
Explanation:
When an Apex class does not achieve the expected code coverage, it suggests that the test methods are not executing parts of the class. The @testvisible annotation can be used to increase code coverage by allowing test methods to access private or protected members of another class. This enables the test method to call methods that may not be directly accessible, but it is not a direct means to generate code coverage. The code coverage is actually achieved when the test methods execute the code within these methods. Therefore, to properly generate code coverage, the developer must ensure that the test methods call the relevant portions of the code that need to be covered. The use of @testvisible can facilitate this process by making otherwise inaccessible code available for testing.

Refer to the test method below''
The test method calls a web service that updates an external system with Account information and sets the Accounts integration_Updated__c checkbox to True when it completes. The test fails to execute and exits with an error: "Methods defined as TestMethod do not support Web service callouts." A) B)
C)
D)

The correct order in tests with callouts is Test.startTest(), then Test.setMock(), followed by the method invocation, and finally Test.stopTest(). This ensures the mock callout is used.
NEW QUESTION # 191
A developer wrote a class named asccuntRisteryManager that relies on field history tracking. The class has a static method called getaccountHistory that Lakes in an Account as a parameter and returns a list of associated accountHistory object records.
The following test fails:
What should be done to make this test pass?
Answer: C
Explanation:
To make the test pass, @isTest(SeeAllData=true) should be used to allow the test to access historical data from the org. This is required because field history tracking data is not copied to a test context, so you need to allow the test to access live data to assert against it.
NEW QUESTION # 192
Universal Containers has an Apex trigger on Account that creates an Account Plan record when an Account is marked as a Customer.
Recently a record-triggered flow was added so that whenever an Account is marked as a Customer, a "Customer Since' date field is updated with today's date. Since the addition of the flow, two Account Plan records are created whenever the Account is marked as a Customer.
What might cause this to happen?
Answer: B
Explanation:
If a flow is configured to evaluate when a record is created and every time it's edited, and an Apex trigger also fires upon the same conditions, it could result in duplicate operations. In this case, two Account Plan records are created because both the flow and the trigger execute upon the Account being marked as a Customer.
NEW QUESTION # 193
A developer is trying to decide between creating a Visualforce component or a Lightning component for a custom screen.
