Test Your Platform Event Trigger in Apex
Ensure that your platform event trigger is working properly by adding an Apex test. Before you can package or deploy any Apex code (including triggers) to production, your Apex code must have tests and sufficient code coverage. To publish platform events in an Apex test, enclose the publish statements within Test.startTest() and Test.stopTest() statements. -
