TestMQ affords the ability to track and log Websphere MQ messages. This provides considerable benefit in the testing of processes that use this technology due to the fact that once a message is received it can no longer be viewed using the MQ browse function. Messages can be tracked when they are sent as part of a TestBench Test Case or alternatively all messages sent to a Queue Manager can be tracked regardless of whether or not a Test Case is running. This enables messages that are sent by non-iSeries functions to be analysed.
There are five different types of MQ functions that can be tracked by TestMQ:-

• MQPUT which puts multiple messages on the MQ Queue.
• MQGET which receives multiple messages from the MQ Queue.
• MQPUT1 which puts a single message on an MQ Queue and then closes the queue immediately afterward.
• MQCMIT – which indicates to the Queue Manager that all of the message gets and puts that have occurred since the last syncpoint are to be made permanent.
• MQBACK which indicates to the Queue Manager that all of the message gets and puts that have occurred since the last syncpoint are to be backed out.
