Lesson 09 - Manual Testing Concepts - What is Boundary Value Analysis (BVA)

A black box testing technique in which focus of testing is on boundary values of the input.
This technique is applied when input is a range.
(Age 18-35 , GuestInRoom 2-5)

It is very likely that application will not function correct when boundary values are supplied. So boundary testing helps tester to detect those bugs.

Here is how inputs are devised for the boundary value analysis.
The tester is supposed to take following inputs.
Minimum - 1,
Minimum,
Minimum + 1,
one value between the range,
Maximum - 1,
Maximum,
Maximum + 1

Example: Suppose, There is a field "Age" in a form which accepts the value between 18 and 35.
The inputs here would be like mentioned below.

17 (Minimum - 1)
18 (Minimum)
19 (Minimum + 1)

27 (one value between the range)

34 (Maximum - 1)
35 (Maximum)
36 (Maximum + 1)
