Equivalence Class Partition Splits The Given Input Into 2
Classes..
Class 1: Valid
Class 2: Invalid

EX:The maximum amount can be withdrawn from ATM machine is
100 to 15,000


Invalid Valid Invalid

-----------100--------------15000--------
Note: Total Number of Test Cases is 3 (2 Invalid and 1 Valid)

Answer / totad

Example for Equivalence Class Partion

Squre root

squre root of all +ve numbers are real(valid)
and squre root of all -ve numbers are imaginay (invalid)

Answer / sudhakar8

An equivalence class is a subset of data that is
representative of a larger class. Equivalence partitioning
is a technique for testing equivalence classes rather than
undertaking exhaustive testing of each value of the larger
class. For example, a program which edits credit limits
within a given range (1,000 - 1,500) would have three
equivalence classes:

< 1,000 (invalid)
Between 1,000 and 1,500 (valid)
> 1,500 (invalid)

Answer / ramanji

Equivalence Class Partion defines all the valid and invalid
values of test data for specific scenario.

EX:Scenario for User id which allows only alphanumerics and
special character"_" only

data matrix for user id field:

valid data:A-B,a-b,0-9,_
Invalid data:All special characters other than "_"

Answer / swetha

ex:The maximum amount can be withdrawn from ATM machine is
15,000
Now accoording to eqivalance partitioning input has to be
given in the different ranges like
1. 0-5000
2.5000-10000
3.10000-15000

In eqivalance partitioning positive scenarios will be
tested as above.

In boundary value analysis negative cases also added like
<0
between 0-15000
>15000

Are there more defects in the design phase or in the coding phase?
