what is boundary value analysis?

Answer Posted / 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.
