Test different input values by populating primitive collections directly in the Flow Builder debugger. Previously you could only test single input values, not collections. Try various scenarios without editing your flow, reducing development time and improving test coverage. For example, if your screen flow or autolaunched flow accepts a text collection of IDs as an input variable, you can now populate that collection directly in the flow debugger.
Where: This change applies to Lightning Experience in Starter Suite, Pro Suite, Enterprise, Performance, Unlimited, and Developer editions.
How: From Setup, in Quick Find, enter Process, and then select Process Automation Settings. Then, select Flow Test Mode (Beta).
In Flow Builder, open a flow that takes primitive collections as input variables. Open the debug panel and populate values for your primitive collection variables. The debugger uses these values for the test run without modifying your flow.
