When you are ready to test your application, you can use the Data Player command-line interface to write scripts and unit tests to exercise the API layers. In some cases it might be easier to play back events to the correlator using the command-line interface as compared to using the Data Player GUI in Apama Studio.

To use the command-line interface to the Data Player, you must have already used the GUI interface in Apama Studio to define queries and query configurations in Apama Studio. When you use the command-line interface, you specify the query names and query configurations that you created in Apama Studio.

For more information on using the Data Player command line interface, see Using the data player command-line interface in Deploying and Managing Apama Applications.
