A. B.B.
Explanation/Reference: The test scripts are mandatory, not optional.
The statement is partially true. In Salesforce, Apex offers the creation of test scripts that can be run in a dev environment. These tests are known as Apex test classes, and they are required to test Apex code before deploying it to production.
Apex test classes are written in Apex and can be executed using the Salesforce user interface (UI) or by Salesforce support personnel. The primary purpose of Apex test classes is to ensure that the Apex code meets the requirements, functions correctly, and does not cause any unforeseen problems.
When Apex code is deployed to production, Salesforce requires that a minimum of 75% of the code is covered by test classes. This rule is called the Apex code coverage rule and is intended to ensure that Apex code is thoroughly tested before deployment. If the code coverage rule is not met, the deployment will fail.
Therefore, creating and running Apex test classes is a critical part of the Salesforce development process, and it is necessary to ensure that the Apex code is thoroughly tested and meets the necessary requirements. So, the statement is true.
