Testing
It is integral part of any system’s development life cycle
without which the system developed is sure to fail and result in loss of
economic and manpower investments besides user’s dissatisfaction and downfall
of reputation.
System testing is the stage of
implementation, which aims at ensuring that the system works accurately and
efficiently before actual operation commences. No program or system design is
perfect, communication between the user and the designer is not always complete
or clear. All this can result in errors.
Another reason for system testing
is its utility as a user oriented vehicle before implementation. The
application system is worthless if does not meet user needs, thus the system
should be tested to see whether it meets the user requirements.
Testing here is conducted in
bottom up approach as follows:
Ø
Module testing: Here testing is done at each
module level. Each case has been throughly tested to discover pitfalls.
Ø
System testing: Here testing is done after all
the modules have been integrated.
