Hi,
There will be testings like Unit testing, Integration testing and User acceptance testing.....
Unit testing means testing of configuration and various developments done independently for your module.
Integration testing is testing of the above including other modules like these are working fine and ensuring not having any adverse effect on other modules processes and flows.
User acceptance testing is the testing done by the key users or end users and they ensure everything working fine as per the design and their expectations....
RICEFW:
R --- Reports
I ----- interfaces
C --- Conversions
E ----- Enhancements
F ----- Forms
W ----- Workflows....
Thanks
Kumar
