Email Testing Functionality in Oracle Fusion Application

In the on-premise Oracle EBS system (another Oracle ERP application), we can use SQL to resend email notifications to the users. The system can generate a test email via the Workflow Mailer, send it to the user, and allow the user to reply to it, it can be use to validate both outbound and inbound email processes are functioning correctly.  

I would like to know whether Oracle Fusion Applications support the same email testing functionality as Oracle EBS. The reason for this is because some suppliers reported that they did not receiving PO email notifications from our procurement department, which buyers don't have the confidence in the Fusion email system. If such a feature exists, users can regularly conduct the email testing to ensure email notifications are functioning correctly.
