value analysis testcasees and equivalence class testcases

Answer Posted / biswal

a)Boundary Value Analysis and Equivalence Classes are two
techniques in Black Box Testing.

b)while writing Test Cases we can use these two techniques.

Boundary value Analysis:
It is nothing but a selection
technique in which testdata are chosen to lie along certain
boundaries.
That is imagine you have to write
test cases for a login field. which will accept 1-10
characters.So if u use boundary value analysis u have to
check with the boundaries that is test with 1 character and
10 characters.then check with 2 characters and 9 characters
and check without any character and with 11 characters.

So that means when u are using the
boundary value analysis that time u have to check withe
lower boundary,lower bolundary+1,Lower boundary-1,Upper
boundary,Upper Boundary-1,Upper Boundary+1.(ie
0,1,2,9,10,11)

Now Equivalence Partitioning:
Equivalence partitioning again is
also a technique.But here we are using with class not with
a value.
if you have to test a field which
will accept 1-10 numbers,then test with positive class (1-
10_,negative class (<1) and (>10).so checking with any
value from the positive equivalence class 1-10 will give
the correct result and checking the result with negative
class will be same for all the values in the negative class.

Hope now you are clear...
Thanks...
