問題 #100
A software company uses a custom object, Defact__c, to track defects in their software. Defect__c has organization-wide defaults set to private. Each Defect_ c has a related list of Reviewer < records, each with a lookup field to User that is used to indicate that the User will review the defect__c.
What should be used to give the User on the Reviewer_c record read only access to the Defect__c record on the Reviewer_c record?
答案：C
解題說明：
Apex managed sharing is used to programmatically share records when organization-wide defaults are private. It allows for creating share records that give read-only access to users specified in a related list.
問題 #101
How should a developer verify that a specific Account record is being tested in a test class for a Visualforce controller?
答案：B
解題說明：
To test a Visualforce controller that works with specific records, you should insert the necessary test data in the test class. Then instantiate a PageReference for the Visualforce page, set the record id in the page parameters, and use System.currentPageReference().getParameters().put('id', recordId) to simulate navigating to the page with that record.
問題 #102
What are three reasons that a developer should write Jest tests for Lightning web components?
Choose 3 answers
答案：C,D,E
解題說明：
Jest tests are essential for developing Lightning Web Components (LWC) because they allow developers to ensure the quality and correctness of their components in isolation from the rest of the application. Reason A is incorrect because testing non-public properties breaks encapsulation and is considered bad practice. B is correct because Jest tests can simulate user interactions with the component, such as clicking buttons or entering text, to ensure it behaves as expected. C is correct as well because Jest tests can confirm that the component renders the expected DOM output, which is crucial for ensuring that the HTML structure of the component is accurate. D is not the best choice since Jest is more suited for testing components in isolation rather than how multiple components interact; integration tests are more appropriate for that. Lastly, E is correct because Jest tests can verify that events are fired at the appropriate times, which is a critical part of the component's interaction with the rest of the application.

問題 #103

答案：A
解題說明：

問題 #104
A developer used custom settings to store some configuration data that changes occasionally. However, tests are now Failing in some of the sandboxes that were recently refreshed.
What should be done to eliminate this issue going forward?
答案：B
解題說明：
Replacing custom settings with custom metadata types is a good solution to ensure that test data is consistent across environments. Custom metadata types are deployable, and their records are available in test methods by default, unlike List Custom Settings which need to be manually recreated in each environment after a refresh.
