When promoting a user story with Apex components set to RunSpecifiedTests, what will happen in production?

When promoting a user story with Apex components set to RunSpecifiedTests in a production environment, it’s important to understand how Salesforce handles unit tests during deployment.

The correct option entails that all tests are executed independent of the specified test settings. This is a requirement imposed by Salesforce to ensure the integrity and stability of all custom code present in the production environment. The platform automatically runs all unit tests in the organization, resulting in greater assurance that the changes made will not adversely affect the existing configurations or functionality.

The security and functionality of an organization depend heavily on proper testing, which is why Salesforce enforces the execution of all tests regardless of specific test settings defined during deployment. This helps prevent potential issues that could arise from new changes interacting negatively with existing code.

In contrast, some other options suggest that no tests would be run, only specific tests would be executed, or that only static tests would be enforced. These options misrepresent Salesforce's deployment requirements and the importance of running all tests to maintain overall system integrity during the introduction of new code changes.
