Answer / sowmya
equivalence class partition is a subset of data that
represents a larger class
EX: Credit card limit ($10,000 and $15000)
less than- 10,000 invalid
equal to ($10,000 and not as greater as 15000) valid
$15,000 or greater invalid

Answer / sanjana
equivalence partition is a black box technique for writting
test cases.
equivalence partition is process of reducing the hung
(infinite) set of possible into much smaller but still
equally effective.
In other word partition input condition which is tested,
where each class representative(cover) a large set of other
possible tests.
In equivalence partion:-
1) Range :- one valid two invalid
2) specific set:- one valid one invalid.
3) number:- one valid two invalid

Answer / narender kaushal
Equivalence class partitioning
Equivalence partitioning is a method for deriving test
cases. In this method, classes of input conditions called
equivalence classes are identified such that each member of
the class causes the same kind of processing and output to
occur. If the system were to handle one case in the class
erroneously, it would handle all cases erroneously.
Equivalence partitioning drastically cuts down the number
of test cases required to test a system reasonably. It is
an attempt to get a good 'hit rate', to find the most
errors with the smallest number of test cases.

Answer / smi
1) If an input condition specifies a range, one valid and
two invalid equivalence classes are defined.
2) If an input condition requires a specific value, one
valid and two invalid equivalence classes are defined.
3) If an input condition specifies a member of a set, one
valid and one invalid equivalence class are defined.
4) If an input condition is boolean, one valid and one
invalid class are defined.

Answer / mfsi_chinmayb`
>Equivalence partitioning , a Black box Technique , is done
mostly on Data inputs derived from the requirement
specification.It is done rarely on Output data.
>The set of input datum are divided into certain classes
having equivalent property.
Like : Certain inputs are Valid inputs and others are
invalid ones.
>The partitions may done upon different property depending
upon the requirements.
>It helps in avoiding Exhaustive testing.

Answer / er. prashant
Equivalence partitioning is a black-box testing method that
divides the input domain of a program in to classes of data
from which test cases can be derived. An ideal test case
single-handedly uncovers a class of errors ( e.g. incorrect
processing of all character data) that might otherwise
require many cases to be executed before the general error
is observed. Equivalence partitioning strives to define a
test case that uncovers classes of errors, thereby reducing
the total number of test cases that must be developed.

Answer / gajanan niture
EC means A group that consists of a set of inputs & every element in the group produces a same output.
A tester will understand the business rules then he asses all possible data & this data can be divided into EC. While dividing the data make sure that every element in a group produces same output. So, that all elements that belongs a group will have the equal amount of priority for testing a feature. So we know need to test with all inputs. One input from every group is sufficient for testing.

Hi harish n Satish...thanx for the response... Already told Functionality testing and user interface type testing to interviewer but he was expecting something else. And also explained test cases....Is it data driven testing for user id and password combinations? If i am not wrong....?
