NEW QUESTION # 79
A developer creates a Lightning web component that imports a method within an Apex class. When a Validate button is pressed, the method runs to execute complex validations.
In this implementation scenario, which two options are part of the Controller according to the MVC architecture?
Choose 2 answers
Answer: A,D
Explanation:
In the Model-View-Controller (MVC) architecture applied to a Lightning Web Component (LWC) that imports an Apex method:
Controller refers to the logic that handles input and interactions.
In this scenario, when a button is pressed, the method runs to execute complex validations.
Option C: Apex class
Part of Controller.
The Apex class contains the method that performs the complex validations.
It acts as the server-side controller logic.
The JavaScript file of the LWC handles the client-side logic.
It invokes the Apex method when the button is pressed.
The HTML file defines the component's template (View), not the Controller.
Option B: XML file
Configuration File.
The XML file (configuration file) defines metadata about the component, such as where it's available, but it's not part of the Controller.
Conclusion:
The Controller parts in this scenario are the Apex class and the JavaScript file, which are Options C and D.
Reference:
Calling Apex Methods
Option D: JavaScript file
Part of Controller.
JavaScript Controller in LWC
Incorrect Options:
Option A: HTML file
View Layer.
NEW QUESTION # 80
A developer is asked to write helper methods that create test data for unit tests.
What should be changed in the TestUtils class so that its methods are only usable by unit test methods?
Answer: B
Explanation:
To ensure that the TestUtils class and its methods are only accessible by unit test methods, the class must be annotated with the @isTest annotation. This annotation limits the scope of the class and its methods to test contexts only.
Why @isTest?
* Purpose of @isTest:
* The @isTest annotation marks a class or method for use exclusively within test scenarios. It prevents the methods from being accidentally invoked in production code.
* This ensures better test isolation and prevents misuse.
* Static Test Data Methods:
* Marking helper methods for test data creation as @isTest ensures they do not interfere with production code and are strictly for testing purposes.
Analysis of Options:
* Option A: @isTest above line 03:
* Incorrect. Applying @isTest only to the createAccount method would work, but the other methods in the class would still be accessible. This does not satisfy the requirement of restricting the entire class.
* Option B: Add @isTest above line 01:
* Correct. Annotating the class ensures all methods within the class are accessible only in the context of tests.
* Option C: Change public to private on line 01:
* Incorrect. Changing the class to private would cause a compilation error, as top-level classes in Salesforce cannot be declared private.
* Option D: Remove static from line 03:
* Incorrect. Removing static does not affect the test scope of the class or its methods. Static methods can still be invoked, and this does not restrict access to test contexts.
Correct Implementation:
The corrected code would look like this:
@isTest
public class TestUtils {
public static Account createAccount() {
Account acct = new Account();
// Set some fields on acct
return acct;
}
// Other methods...
}
