Methods, systems, and computer-readable media are disclosed herein for enabling inbound testing. Aspects herein provide a tool that can, from with a single application, generate test HL7 transaction messages and send the generated test HL7 messages to an inbound testing interface to monitor performance of a testing interface. The tool provides a mechanism to generate a large number of test HL7 messages having different identifier types and message types simultaneously. The tool also provides a mechanism to send large numbers of test HL7 messages, of different identifier types and message types, simultaneously, to a testing environment via multiple pipes.
