What allows multiple tests to be run against the same record in the design environment?

Simulated triggers are a key feature that facilitates running multiple tests against the same record in the design environment of ServiceNow. This functionality allows developers and testers to invoke flows as if specific events occurred without actually having to create those events in the system. By using simulated triggers, they can test how the flow reacts under various conditions or inputs, improving development efficiency and ensuring that the flow behaves as expected before it is deployed into a live environment.

The ability to test different scenarios on a single record is crucial for validating the logic and outcomes of workflows, and simulated triggers provide the necessary flexibility to do so effectively. This is particularly important in continuous development processes where quick iterations and thorough testing are required.
