what is testing

Answer Posted / shyam g

In general, testing is finding out how well something
works. In terms of human beings, testing tells what level
of knowledge or skill has been acquired. In computer
hardware and software development, testing is used at key
checkpoints in the overall process to determine whether
objectives are being met. For example, in software
development, product objectives are sometimes tested by
product user representatives. When the design is complete,
coding follows and the finished code is then tested at the
unit or module level by each programmer; at the component
level by the group of programmers involved; and at the
system level when all components are combined together. At
early or late stages, a product or service may also be
tested for usability.

I know functional test cases are derived from frs and system design specs. But are test cases for performance, database, boundary, relational integrity and other types of tests other than functional tests created from frs and system design specs as well? When are these test cases created? Are they in the same test plans alongside functional test cases or is their a different test plan that includes these test cases?
