How to Test platform Event Trigger Flow

Question

I have a flow which subscribes to a platform Event. This flow consumes the event and inserts a record. My test class is:

Test.startTest();
            
Database.SaveResult result = EventBus.publish(testEvent);
System.assertEquals(true, result.isSuccess());  
Test.getEventBus().deliver();

Test.stopTest();

It looks like only Apex triggers are running after the Test.getEventBus().deliver() statement while Flow is not at all getting triggered. I thoroughly checked the logs and there is no logs of the Flow running. I checked that the Flow is Active. Salesforce explicitly says that flows are triggered from apex test class here: https://developer.salesforce.com/docs/atlas.en-us.platform_events.meta/platform_events/platform_events_test_events.htm

Answer 1

Use this query to check the flow is subscribed to the platform event.

SELECT Name, Position, Retries, LastError FROM EventBusSubscriber

If its not listed, save a new version of the flow. I ran into this on a newly created sandbox
