Boundary value analysis is nothing but writing cases in which data varaible have the value on both the extreme.

For example, if you writing a test cases for the condition of salary should be greater than 10,000 & less than 15,000.. at that time we have to wirte the test cases for 9999, 10000, 10001 & 14999, 15000, 15001

boundry value analysis is a technique in functional testing for writing test cases..where we can test our functionality with some input like...min value,min+1,min-1,max,max+1,max-1

BVA is testing at boundary conditions to validate conditions. There is always a higher probability of finding errors at boundary. The main reason for this is use of wrong conditions.

For eg. imagine a condition where user can input valid range is 1000 to 1500. Here, developer may write logic as 1000 < X < 1500. Note that correct logic should be 1000 <= X <= 1500.

To test this range tester should test with input values as 999, 1000, 1500, & 1500.

Note that there is no need to test using 1001 & 1499. If a test passes properly for 1000 & 1500 then logically it will pass for 1001 & 1499 also, until & unless they are part of some other equivalence class.
