NEW QUESTION # 34
A developer needs to create a baseline set of data (Account, Contacts, Products, Assets) for an entire suite allowing them to test independent requirements for various types of Salesforce Cases.
Which approach can efficiently generate the required data for each unit test?
- A. Add $ IsTest (seeAllDatatrue) at the start of the unit test class.
- B. Create test data before Test.startTest in the unit test.
- C. Create a mock using the Stub APL.
- D. Use &TestSteup with a void method.
Answer: D
Explanation:
To efficiently generate the required data for each unit test, the best approach is to use @TestSetup with a void method. This annotation allows you to create common test data that is available for all test methods in the test class. The data is rolled back after each test method, so you don't have to worry about deleting or modifying it.
This way, you can avoid duplicating code and improve performance by reducing the number of DML operations. The other options are not correct because:
* Creating test data before Test.startTest in the unit test means that you have to repeat the same code for every test method that needs the same data. This can make your test class longer and harder to maintain.
It also consumes more DML statements and governor limits.
* Creating a mock using the Stub API is useful for testing callouts or interfaces, not for creating test data.
A mock object is a fake object that simulates the behavior of a real object. It does not persist any data in the database.
* Adding @IsTest(seeAllData=true) at the start of the unit test class is not a good practice, as it makes your test methods depend on the data in the org. This can cause your tests to fail or behave inconsistently if the data changes or is not available. It also exposes your test methods to the risk of violating data privacy or security policies.

How should this be accomplished?
- A. Call a method in the Apex controller.
- B. Update a property on the parent.
- C. Fire a notification.
- D. Create a custom event,
Answer: D
Explanation:
To notify the parent component from a child component when a button is clicked:
Option C: Create a custom event
Child Component:
// ChildComponent.js
handleClick() {
const nextEvent = new CustomEvent('next');
this.dispatchEvent(nextEvent);
}
Parent Component:
<!-- ParentComponent.html -->
<c-child-component onnext={handleNext}></c-child-component>
javascript
Copy code
// ParentComponent.js
handleNext() {
// Navigate to the next page
}
Reference:
"To communicate up the component containment hierarchy, fire a custom event in the child component."
- Lightning Web Components Developer Guide: Communicate with Events
Why Other Options Are Incorrect:
Option A: Updating a property on the parent directly is not possible from the child.
Option B: "Fire a notification" is vague and not a standard mechanism.
Option D: Calling a method in the Apex controller does not facilitate child-to-parent communication within components.

Universal Container wants Opportunities to no longer be editable when itreaches the Closed/Won stage.
Which two strategies can a developer use to accomplish this?
Choose2 answer
- A. Use the Process Automation settings.
- B. Use a validation
- C. Use a trigger
- D. Use an after-save flow.
Answer: B,C
Explanation:
A developer can use a validation rule or a trigger to prevent Opportunities from being edited when they reach the Closed/Won stage. A validation rule can check the stage value and display an error message if the user tries to modify the record. A trigger can also check the stage value and throw an exception if the user tries to update the record. Both of these strategies can enforce the business logic at the database level and prevent unwanted changes.
An after-save flow or the Process Automation settings are not suitable for this requirement, because they are executed after the record is saved to the database. They can perform actions based on the record changes, but they cannot prevent the record from being edited in the first place.
