Which test type would likely be a part of a typical automation setup?

The option identifying APEX Tests with Validation is relevant in the context of a typical automation setup because APEX tests are designed to automatically validate the functionality and efficiency of code written in Salesforce's proprietary programming language, Apex. Automated testing is fundamental to ensure that deployed changes do not break existing functionality and that new features perform as expected. By executing APEX tests as part of an automation pipeline, developers can quickly receive feedback on the integrity of their code, ensuring that any issues are caught early in the deployment process.

In contrast, other test types mentioned may not fit seamlessly into an automation setup. Manual Approvals involve human intervention and decision-making, which limits automation opportunities. Version Control Tests, while important in managing code changes, are not a direct form of testing like APEX tests. User Acceptance Tests, typically carried out by end users to confirm functionality aligns with their expectations, also require manual actions and feedback, making them less suited to an automated testing environment. Thus, APEX Tests with Validation stands out as the most conducive option for automation.
