If you are writing test case then you need input data for
any kind of test. Tester may provide this input data at the
time of executing the test cases or application may pick
the required input data from the predefined data locations.
The test data may be any kind of input to application, any
kind of file that is loaded by the application or entries
read from the database tables. It may be in any format like
xml test data, system test data, SQL test data or stress
test data.

Design your test data considering following categories:
Test data set examples:
1) No data: Run your test cases on blank or default data.
See if proper error messages are generated.

2) Valid data set: Create it to check if application is
functioning as per requirements and valid input data is
properly saved in database or files.

3) Invalid data set: Prepare invalid data set to check
application behavior for negative values, alphanumeric
string inputs.

4) Illegal data format: Make one data set of illegal data
format. System should not accept data in invalid or illegal
format. Also check proper error messages are generated.

5) Boundary Condition data set: Data set containing out of
range data. Identify application boundary cases and prepare
data set that will cover lower as well as upper boundary
conditions.

6) Data set for performance, load and stress testing: This
data set should be large in volume.

This way creating separate data sets for each test
condition will ensure complete test coverage.

Answer / vijay

In my project whether writing the test conditions itself we
will create the test data.

Test data means when we are executing the test scripts,we
need to give some input for required fields.those inputs
are called as test data.

I am in Insurance domain project, while writing the test
case itself,I know,which type of policy I need to test the
perticular condition.

If I have no required data in test region, I will request
to the supporting team to load in test region from Live.

If I am wrong Please let me know

Hi Mr,
The source of the Test data differs from Phases to Phases,
If you are in IAT then extract data from Design docs,
if you are in System testing( functional or non
functional ) get the data from SRS and if you are in UAT,
then get data from BRS or some times you are allowed to use
live data.
