NEW QUESTION # 131
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?
Answer: D
Explanation:
5
The iss6ue described is a direct result of how Salesforce treats data during sandbox refreshes and unit testing.
Custom Settings (both List and Hierarchy) store their information as data records. By default, sandbox refreshes do not include data records from Production unless it is a Full Sandbox. Furthermore, Apex unit tests are isolated from organization data; they cannot "see" Custom Setting records unless the records are explicitly created within the test or the @isTest(SeeAllData=true) annotation is used (which is a poor practice).
Custom Metadata (Option C) solves this by treating configuration records as metadata rather than data.
Because they are metadata, the records are automatically included in every sandbox refresh and are deployable via Change Sets or the Salesforce CLI. Most importantly, Custom Metadata is visible to Apex unit tests without needing to create setup data or bypass test isolation. This ensures that configuration-dependent logic remains consistent across all environments and that tests pass reliably after a refresh. Replacing Custom Settings with Custom Metadata is the modern Salesforce standard for environment-independent configuration management.
NEW QUESTION # 132
A developer created and tested a Visualforce page in their developer sandbox, but now receives reports that users are encountering ViewState errors when using it in Production. What should the developer ensure to correct these errors?
Answer: B
NEW QUESTION # 133
A company has a custom component that allows users to search for records of a certain object type by invoking an Apex Controller that returns a list of results based on the user's input. When the search is completed, a searchComplete event is fired, with the results put in a results attribute of the event. The component is designed to be used within other components and may appear on a single page more than once.
What is the optimal code that should be added to fire the event when the search has completed?
Answer: A
NEW QUESTION # 134
In a VisualForce page with a VisualForce component that has rendered set to false when the page loads, how can a developer ensure it will show on a re-render?
Answer: C
NEW QUESTION # 135
A developer created 2 class that implements the Queueable Interface, as follows:
As part of the deployment process, the developer is asked to create a corresponding test class.
Which two actions should the developer take to successfully execute the test class?
Choose 2 answers
Answer: B,D
Explanation:
When writing a test class for a Queueable class in Salesforce, the goal is to ensure that the asynchronous code is executed within the test context and that it does not affect the state of the production org or depend on its data.
* Option C is correct because using Test.startTest() and Test.stopTest() ensures that the asynchronous code is executed immediately within the test's context. This is essential for testing Queueable classes because it allows the test to wait for the asynchronous process to complete before assertions are made.
Without this, the asynchronous job would not necessarily run during the test execution.
* Option D is correct because Test.isRunningTest() can be used within the Queueable class to prevent the chaining of jobs during test execution. Chaining queueable jobs can lead to governor limits being hit and is generally not allowed in test methods. This conditional check allows the developer to bypass sections of the code not suitable for a testing context.
* Option A is incorrect because the seeAllData=True annotation is not required for testing Queueable classes, and it is not a best practice to depend on live data for tests. It's preferable to create test data within the test class itself.
* Option B is incorrect because having the 'View All' permission on the Order object is not related to the successful execution of the Queueable class in tests. Permissions are typically not enforced in test contexts unless using System.runAs() to test with a specific user context.
