Hi
    Test Data Has to be prepared based on the Requirement.






sun_ramprasad@yahoo.com

data that exists before a test is executed , and that 
affects , or is affected by the component or system under 
test.

Test data is prepared after indepth study of data 
dictionary with a detailed knowledge of system test.

Basically Test data is nothing but input to the 
functionality,We can prepare the test data based on 
Boundary value and Equivalance partioning theories.

Test data is the input data for functionality/system under 
test. Following are the steps one should follow:

1). Identify if the data exists and is usable without 
conflicting with other testers using the application. If not
2). Create your own data
3). In creating the data follow specified procedure/rules 
for the teams using the same application.
ex: ERP application dev:- Emplid should start with "HX" for 
HR team & "PX" for Payroll team etc. (This helps to 
identify which test the employee belongs to)

Test data that satisfy the  given adequacy criterion of the 
project .

Based on the requirements and needful validations we need to
prepare test data
