Till date, CATT could only be used with the R/3 system. eCATT (which is available with SAP Web Application Server 6.20) covers the automatic testing in SAPGUI for Windows and SAP GUI for Java. For other GUIs and Applications, eCATT provides an interface for external tools. This allows companies to perform automated tests from an SAP system in a complete IT solution landscape across system boundaries. These new options enable complete automation of solution landscapes under standard Windows and Web-based user interfaces- resulting in low-cost operation of an IT Solution.
