The test request message is utilized to force a heartbeat from the opposing application. The test request message is useful for checking sequence numbers or verifying the communication line status. The opposite application will respond to the Test Request with a Heartbeat.
The TestReqID is used to verify that the oppposite application is generating the heartbeat as the result of Test Request and not a normal timeout. The opposite application will include the TestReqID in the resulting Heartbeat. Any string can be used as the TestReqID (one suggestion is to use a timestamp string).
Sequence numbers are not incremented for test request messages.
