Salesforce Platform Developer Practice Exam

An org has different Apex Classes that provide Account-related functionality. How can a developer resolve test method failures due to a new validation rule?

1. Create a method that creates valid Account records

2. Create a method that loads valid Account records from a Static Resource

3. Create a method that performs a callout for a valid Account record

4. Create a method that queries for valid Account records

The correct answer is: Create a method that creates valid Account records

Creating a method that generates valid Account records is essential in resolving test method failures caused by a new validation rule. When tests run, they operate within the context of the organization’s validation rules, which means that if the test attempts to create or modify an Account that does not meet the validation criteria, it will fail. By implementing a method that constructs valid Account records, a developer ensures that any new records created during the test adhere to the existing validation rules. This approach allows the testing process to run smoothly, verifying the functionality of the Apex classes without being interrupted by validation rule violations. Moreover, constructing valid records within the test method aligns with best practices for testing in Salesforce. It ensures that the tests truly reflect the conditions under which the application will operate in the live environment. Methods that load records from static resources, perform callouts, or query existing records may not guarantee that the records meet the new validation rules or the specific requirements of the test scenario. These alternatives could introduce additional complexities or fail to adequately resolve issues stemming from validation rules, which is why creating valid records directly is the most effective solution.
