    TestRequest (1)

    ID2
    PedigreeAdded FIX.2.7, Updated FIX.4.0

    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 communication line status. The opposite application will respond to the Test Request with a Heartbeat containing the TestReqID.

    The TestReqID is used to verify that the opposite 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).
