Stubbing

[meena latha]

Hi all.
I have no clear idea what this stubbing really means.
When i google i can to know that stubbing is done for testing data that are very expensive ..etc .And stubs are different for mocks.
But i not confused and do not have a clear picture.
Is there any link that i can look into to get in details or can anybody explain me what is stubbing and where it is used and so on.
Thanks

Martin Fowler has written a pretty good short article that describes the difference between stubs and mocks.
