NEW QUESTION # 30
Refer to the code snippet below:
import fetchOps from ' @salesforce/apex/OpportunitySearch.fetchOpportunities ' ;
@wire(fetchOps) opportunities;
When a Lightning web component is rendered, a list of opportunities that match certain criteria should be retrieved from the database and displayed to the end-user.
Which three considerations must the developer implement to make the
fetchOpportunities method available when Lightning web component?
Answer: A,D,E
Explanation:
Answers A, C, D are correct. Lightning Web Components use modern web standards with Salesforce-specific modules, decorators, base components, and Lightning Data Service integration. Parent components pass data down through public properties or public methods, while children communicate upward with custom events.
Apex methods imported from @salesforce/apex must be annotated correctly and wired methods must be cacheable. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint. For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Lightning Web Components Developer Guide, Lightning Component Reference, Aura Components Developer Guide, and Visualforce Developer Guide. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.
NEW QUESTION # 31
A developer at AW Computing is tasked to create the supporting test class for programmatic customization that leverages records stored within the custom object, Pricing_Structure__c. AW Computing has a complex pricing structure for each item on the store, spanning more than 500 records, Which two approaches can the developer use to ensure Pricing Strucrture_c records are available when the test class is executed?
Choose 2 answers
Answer: B,D
Explanation:
To ensure Pricing_Structure__c records are available when the test class is executed, the developer can use the following approaches:
Option A: Use a Test Data Factory class.
Valid Approach.
A Test Data Factory class is a utility class that creates test data for use in test methods.
It helps in generating consistent test data and promotes reusability.
The factory class can create the necessary Pricing_Structure__c records for testing.
Test.loadData() allows loading test data from a static resource (CSV file) into test methods.
This is useful for loading large datasets, such as over 500 records.
The CSV file can contain the Pricing_Structure__c records needed for testing.
Using SeeAllData=true accesses existing org data, which is not recommended due to test data isolation.
Tests should create their own data to ensure reliability and avoid dependencies on org data.
The without sharing keyword affects record sharing and visibility, not data availability in tests.
It does not help in creating or accessing test data.
Reference:
Test Data Factory Pattern
Best Practices for Test Classes
Option B: Use the Test.loadData() method.
Valid Approach.
Test.loadData Method
Using Test.loadData()
Incorrect Options:
Option C: Use the @IsTest(SeeAllData=true) annotation.
Not Recommended.
Isolation of Test Data from Organization Data in Unit Tests
Option D: Use without sharing on the class declaration.
Irrelevant.
Using the with sharing or without sharing Keywords
Conclusion:
To ensure Pricing_Structure__c records are available in tests, the developer can use Option A (Test Data Factory) and Option B (Test.loadData()).
