Answer / rajendra
Boundary Value Analysis(BVA):
Normally this will be used to validate the numeric text
boxes(fields).
For example if we take a text box it will accept
Min(say m) 5 chars -Lower boundary
Max(say n) 9 chars -Upper boundary
here the boundaries are 5 and 9.
(min-1)4--- 5(min)6 -----7-----8------9(Max)---10(max+1)
invalid---><---------Valid range---------><=-invalid--
| |
Bpundary-1 Boundary-2
Then now we will check the text box by giving different
inputs at boundaries
like
Below 5 it must not accept.
Above 9 it must not accept .
for other conditions we will check like
m+1 is acceptable(because 5+1=6)
m-1 is not acceptable(because5-1=4)
n-1 is acceptable(because 8-1=7)
n+1 is not acceptable(because 9+1=10)
and also we can check the middle values between 5 to 9
The middle values must accept.
The real word example is Password field of yahoo mail
it will accept only some number of min characters
and will accept only some number of mix characters

Boundary Value Analysys(BVA)
For example if we take a text box it will accept
Min(say m) 5 chars -Lower boundary
Max(say n) 9 chars -Upper boundary
In this is case we have design the test cases for
(5-1)(5)(5+1)(9-1)(9)(9+1)
(m-1)(m)(m+1)(n-1)(n)(n+1)

Answer / prashanth
Boundary Value Analysis(BVA)is nothing but testing the Minimum and Maximum values of a text box field. Lets take an example
Let's say In Requirements document for "User Name" field it is give like this
- User name field should accept minimum 3 and Maximum 9 alphanumeric characters should accept
In Use Case document it will be written like below
User name Field:BVA
- min-1 is Invalid (2)
- min= is valid (3)
- min+1 is valid (4)
- max-1 is valid (8)
- max= is valid (9)
- max+1 is Invalid (10)
In Test Case document we write like this
Test Case_001:
Enter 2 values in User name field and click on Submit button
Expected: Error message should display "Enter Valid User Name"
Test Case_002:
Enter 3 values in User name field and click on Submit button
Expected: Should navigate to particular page
Test Case_003:
Enter 4 values in User name field and click on Submit button
Expected: Should navigate to particular page
Test Case_004:
Enter 8 values in User name field and click on Submit button
Expected: Should navigate to particular page
Test Case_005:
Enter 9 values in User name field and click on Submit button
Expected: Should navigate to particular page
Test Case_006:
Enter 10 values in User name field and click on Submit button
Expected: Error message should display "Enter Valid User Name"
The above format is only example.
