A. Use a collection for the DML statement.
B. Remove the DML statement.
C. Change the trigger context to after update, after insert.
D. Query the Pricing_structure__c records outside of the loop.

Answer: B,D

NEW QUESTION # 92
The test method calls an @future method that increments a value. The assertion is failing because the value equals 0. What is the optimal way to fix this?
Java
@isTest
static void testIncrement() {
Account acct = new Account(Name = 'Test', Number_Of_Times_Viewed__c = 0); insert acct; AuditUtil.incrementViewed(acct.Id); // This is the @future method Account acctAfter = [SELECT Number_Of_Times_Viewed__c FROM Account WHERE Id = :acct.Id][0]; System.assertEquals(1, acctAfter.Number_Of_Times_Viewed__c);
}

A. Change the assertion to System.assertEquals(0, acctAfter.Number_Of_Times_Viewed__c).
B. Change the initialization to acct.Number_Of_Times_Viewed__c = 1.
C. Add Test.startTest() before and Test.stopTest() after insert acct.
D. Add Test.startTest() before and Test.stopTest() after AuditUtil.incrementViewed.

Answer: D

Explanation:
Asynchronous methods, such as those annotated with @future, do not run immediately when called in Apex.
Instead, they are added to a queue to be processed when system resources become available. In a unit test, if you call a future method and immediately query the database for the result, the future method likely hasn't executed yet, resulting in the "0" value observed in the assertion.
To test asynchronous code, you must wrap the call within Test.startTest() and Test.stopTest() (Option D).
When the code reaches Test.stopTest(), the execution of the test script pauses, and the system forces all queued asynchronous jobs (future methods, batch jobs, queueable jobs) to run to completion synchronously.
By placing the AuditUtil.incrementViewed(acct.Id) call inside this block, you ensure that by the time the next line of code (the SOQL query) runs, the increment logic has finished and the database reflects the new value.
Option B is incorrect because inserting the account is a synchronous operation that doesn't require the stopTest wait. Option A and C avoid the problem rather than testing the logic correctly. Option D is the standard platform-required pattern for testing asynchronous side effects.

NEW QUESTION # 93
A developer has created the following trigger: trigger ProcessDoNotCall on Contact (after update) { List<Contact> lstCon = [SELECT Id, DoNotCall, Department FROM Contact WHERE Department = 'HR' AND Id IN :Trigger.new]; for(Contact c : lstCon) c.DoNotCall= true; update lstCon; } The developer executes the following code anonymously in the Developer Console. Assume that the record exists in Salesforce.
Contact con = new Contact(Id='003oOOOOOOVHXOm',Department = 'HR') update con; Which behavior will the developer observe?

A. The code will throw an exception in Anonymous Apex, indicating that the Id field is read-only.
B. The code will throw an exception because the maximum trigger depth has been exceeded.
C. The code will throw an exception, saying that the record cannot be updated in an After Update trigger.
D. The contact record will be saved and the contact record's DoNotCall field will be set to true.

Answer: B

NEW QUESTION # 94
Which statement is true regarding savepoints?

A. Reference to savepoints can cross trigger invocations.
B. Static variables are not reverted during a rollback.
C. Savepoints are not limited by DML statement governor limits.
D. You can roll back to any savepoint variable created in any order.

Answer: B

Explanation:
When rolling back to a savepoint, any DML operations that occurred after that savepoint are undone, but static variables are not reverted. Therefore, when a rollback occurs, the state of all static variables at the time of the rollback remains the same as it was just before the rollback.References: Apex Developer Guide - Savepoint and Transaction Control
