Hi,

Unit testing is refer to the module which are going to implement. SD, MM, FICO etc. there will be test script based on that testing will be performed.

Integration testing will be cross the modules. MM-SD-FICO for example. Integration testing is also called SIT ( System integration testing

Unit testing is done in bit and pieces. Like e.g. in SD standard order cycle; we do have 1-create order, then 2-delivery, then 3-transfer order, then 4-PGI and then 5-Invoice. So we will be testing 1,2,3,4 and 5 seperately alone one by one using test cases and test data. We will not be looking and checking/testing any integration between order and delivery; delivery and TO; TO and PGI and then invoice.

Whrereas System testing you will be testing the full cycle with it's integration, and you will be testing using test cases which give a full cyclic test from order to invoice.

With regards
