Release 3.0 includes the new CATT tool.
CATT (Computer Aided Test Tool) is integrated in the ABAP/4 Development Workbench and makes it possible to group business transactions in test runs and automate them. You can use CATT to create modules for individual transactions and test runs for a complete business process within the SAP System, including all the requirements for a given test.
For more information about CATT refer to the manual Computer Aided Test Tool on the Documentation CD-ROM.
