Answer / rajendra prasad reddy

Some softwares not require GUI (Front End)
These softwrae are called as Middlewares or Engines.
These engines or back end software will be linked to some
front end applications.
These back end software typically process the input
paramaters and generates output(XML form).
To test like this softwares we have to prepare some
interface using HTML forms to post the paramaters for
processing.

For example:
A online shopping site offers different types of products
for sale,
When we click on 'Buy' button the online shopping site will
send customer paramaters to billing engine for processing
transaction.So here the Online shopping portel just
provides a front end and passes the user data to other
billing engine.This data is:
Product ID selected by the user,
Prouct Price,
Time of transaction,
His Credit card Number..etc.
So billing engine processes the transaction and returns the
transaction status to shopping portal.
ok

Let us assume that your front end application is yet to
ready where you can perform the test. Still you can
interact with the database where the data is going to be
stored using structured query langues. You can peform most
of the operations like insert, retired, delete data
into/from the tables. You can also perform the filter
operations using conditions.
