PDI Question #137: Real Exam Question with Answer & Explanation

Question

A developer wants to get access to the standard price book in the org while writing a test class that covers an OpportunityLineItem trigger. Which method allows access to the price book?

Options

• AUse Test.loadData ( )and a static resource to load a standard price book
• BUse @TestVisible to allow the test method to see the standard price book.
• CUse Test.getStandardPricebookid ( ) to get the standard price book ID.
• DUse @IsTest (SeeAllData=True) and delete the existing standard price book

Explanation

To access the ID of the standard price book within a test class in Salesforce, developers should utilize the Test.getStandardPricebookId() method.

Common mistakes.

• A. While Test.loadData() can load data from static resources, it is not used to access standard Salesforce setup data like the standard price book ID directly.
• B. @TestVisible is used to allow test methods to access private or protected members of a class, not to retrieve standard Salesforce IDs like the standard price book ID.
• D. @IsTest(SeeAllData=True) exposes all org data, but it is generally discouraged, and deleting the standard price book is not a valid or safe approach to accessing its ID in a test.
