Software Testing Concept-
Software Testing is to
find out a way for- Knowing your customer's requirement completely
for making a software under the budget & time defined for project
to meet the customer's needs exactly.
Software Testing validates( means -are
we making right software) & verifies ( means – are we making
the software right) the software,for following conditions-
1- The software made, is exactly the
replica of the agreement signed between customer & company for
design & development.
2- The customer will be completely
satisfy with the working of software at his end after implementation
.
(
According to IEEE-STD-610
-
Validation:
The process of evaluating software during or at the end of the
development process to determine whether it satisfies specified
requirements.
Verification:
The process of evaluating software to determine whether the products
of a given development phase satisfy the conditions imposed at the
start of that phase. )
According to ANSI/IEEE 1059 standard,
Testing can be defined as -A process of analyzing a software item to
detect the differences between existing and required conditions(that
is defects/bugs/errors) and to evaluate the feature of the software
item.
There are many methods of software
testing. Depending upon these methods,we (test team)decide that at
which state of software development life cycle,we will involve
software testing. But it is always considered good to involve testing
as early as possible so that we can reduce the cost of bugs.
It is like a game , where test team
tries to find out all the odd behaviors(The behavior which is not
needed) of the software made by development team by knitting a strong
trap by using different
test strategies & It is Fun to knit traps for those who are having great mind &
strong skills & are able to use their commonsense to it's fullest .
Thanks !!! :)
