Boundary value focuses on input and output boundaries of a
given fucntion.it consists of developing test cases
Lower boundary
min-1,min

Upper boundary
max max+1
For example if we are checking for we are checking credit
limit between 10,000 and 15,000
the lower boundary will be
9,999 & 10,000
the upper boundary wil be
15,000 & 15,001

Answer / lakshmanaraj bg

‘Boundary value analysis’ testing technique is used to identify errors at boundaries rather than finding those exist in center of input domain.

It’s widely recognized that input values at the extreme ends of input domain cause more errors in system.

More application errors occur at the boundaries of input domain.

Boundary value analysis is a next part of Equivalence partitioning for designing test cases where test cases are selected at the edges of the equivalence classes.

Boundary value analysis is often called as a part of stress and negative testing.

TEST CASES:

1) Test cases with test data exactly as the input boundaries of input domain i.e. values 1 and 1000 in our case.

2) Test data with values just below the extreme edges of input domains i.e. values 0 and 999.

3) Test data with values just above the extreme edges of input domain i.e. values 2 and 1001.

Answer / sandeep gupta

In this technique, all the possible valid input and valid
output are identified.Test cases also include both valid
and invalid inputs.

Answer / ajay

it is an technique used to check the boundary values of an
application....

Answer / saiganpath

This tech used to find out the boundary values and its used
for minimal test cases to cover all the possibilities.

For an example,

User name should be allowed 6 <= 8 characters, here 6 and 8
is positive boundary values and 5 and 9 is the negative
boundary values.

So (6,8)(5,9) total 4 test data we have to prepare to find
boundary value analysis.

Answer / mfsi_priyankaa

It is a black box technique, which is used to identify
errors at the boundaries i.e. n-1, n , n+1.

Answer / sanjana

Boundary values means selection of test cases/input data
which lies on boundary.
In Boundary values we check the limit condition of the
input data.
for number:- one valid two invalid
for range:- one valid two invalid
for set:- one valid one invalid
