can any body explain about BVA and ECP briefly?..

Answer / srikanth yanamandra

Hellow,

BVA - Boundary value analysis

When we have to validate a text field or any other field
whether it is accepting the no of Characters as per the
requirement or not,then we will go for BVA

In BVA, we will test the extream boundaries by taking
max+1 ,min-1 values. If the field behaving correctly for
these extream values then inbetween also works fine.

ECP - Equivalent class partician

When we have to validate whether the field is accepting the
correct data type as per the requirements or not we will go
for ECP

In ECP , we will devide the data as 'Valid' and 'In valid'
Valid data - Integers , numericals ,alpha numericals
Invalid data - Speacial charecters , blank
We will apply both the types and check whether
functionality works correctly or not

Thanks

Answer / srinivas bhamidipati

Srikant,

Your answer for Boundary Value Analysis is correct.

But I want to add further info for ECP:

Equivalence Class Partitioning is used when we have large
sets of data. For Eg : when a field accepts 1-1,00,000,
then we can check ECP testing as equivalent sets such as (1-
20,000), (20,001-40,000), (40,001-60,000), (60,001-80,000),
(80,001-1,00,000). Then, we take the random values fr each
set and test for the random test sample and validate
accordingly. Further more, you can split the same range to
subsets if you feel the risk of not selecting more risk
prone sample.

Thanks

Answer / kalpana

BVA is boundary value analysis...in this will check for
length of the fields like the field will not accept more
than max char length etc and where as

ECP is equivalent class partition ...will check for what are
all the valid and invalid classes like Name field should not
accept special chars etc...
