I think u know product and project. In both we go to same 
type of testing but there is no difference between them. So 
I think there is no product base testing seperately. If u 
know please tell me. hari_babu2050@yahoo.co.in

hari....u r totally wrong...Product based testing is there!!!

so what is the ans.?

Project Based Testing - we get the entire requirements from 
the Client.Perform the testing according to the client 
requirements and return back the with bug free application 
to the Client.

Product based testing - we design a product in such a 
manner it fullfills completely for a single domian.
I was involved in Product Testing for the Product : 
MyFotoBiz.In this product it was our business analayst whio 
performed entire analysis related to photography domain and 
prepared the SRS.
It was then sent to our higher officiala who knows 
completly about the domain. Then after approval the dev cum 
testing work started simultaneously.
we foolowed agile methodology in doing the product based 
testing where in we have implemented the appilcation on a 
sprint basis where in we needed to attend scrum calls on a 
daily absis.

that is all i know....

plz do update me if i am wrong??

I think Produce based testing is nothing but testing a 
product by model customers at model customer site and it is 
applicable to products and not applications. To meet the 
market demand we prepare products and it is of more general 
in nature and not keeping any one individual client. 
Produce based testing is also know as Beta testing.

In project testing, system will be build based on client 
requirements and the requirements will be given by the 
client whereas in product testing, system will be build 
based on domain knowledge and the requirements will be 
gathered by SME/Domain specialists since no clients will be 
there
