Introduction
Software testing is a critical element
of software quality assurance and represents the ultimate process to
ensure the correctness of the product. The quality product always
enhances the customer confidence in using the product thereby increases
the business economics. In other words, a good quality product means
zero defects, which is derived from a better quality process in testing.
Software is an integrated set of Program
codes, designed logically to implement a particular function or to
automate a particular process. To develop a software product or project,
user needs and constraints must be determined and explicitly stated.
The development process is broadly classified into two.
1. Product development
2. Project development
Product development is done assuming a
wide range of customers and their needs. This type of development
involves customers from all domains and collecting requirements from
many different environments.
Project Development is done by focusing a
particular customer’s need, gathering data from his environment and
bringing out a valid set of information that will help as a pillar to
development process.
Testing is a necessary stage in the
software life cycle: it gives the programmer and user some sense of
correctness, though never “proof of correctness. With effective testing
techniques, software is more easily debugged, less likely to “break,”
more “correct”, and, in summary, better.
Most Software Development
processes in the IT industry always seem to follow a tight schedule.
Often, these schedules adversely affect the testing process, resulting
in step motherly treatment meted out to the testing process. As a
result, defects accumulate in the application and are overlooked so as
to meet deadlines. The developers convince themselves that the
overlooked errors can be rectified in subsequent releases.
The definition of testing is not well understood. People use a totally incorrect definition of the word testing, and that this is the primary cause for poor program testing. Read More...
