Boundary value analysis.

In Software Engineering, boundary value and equivalent partition are other similar techniques used to ensure better coverage.They are used if the system shows the same behavior for a large set of inputs.However, in a system where for each set of input values the system behavior is different, boundary value and equivalent partitioning technique are not effective in ensuring good test coverage.

For example, { (partial^2u)/ (partialt^2)-del ^2u=f in Omega; u (0,t)=u_1 on partialOmega; (partialu)/ (partialt) (0,t)=u_2 on ...The goal of boundary value analysis is to focus testing on error-prone areas by precisely pinpointing the boundaries of conditions (for example, a programmer may specify > when the requirement states > or =). To create boundary value analysis test cases, you must first identify which boundaries exist at the interface of a software component. Boundary value analysis - Boundaries are very good places for errors to occur. Hence if test cases are designed for boundary values of the input domain then the efficiency of testing improves and the probability of finding errors also increases.

BVA is considered a technique that uncovers bugs at the boundary of input values. Here, boundary means the maximum or minimum value taken by the input domain. For example, ifA is an integer between 10 and 255 , then boundary checking can be on 10 ( 9, 10, 11) and on 255 ( 256, 25, 254).

Towards Automated Boundary Value Testing with Program Derivatives and Search. Robert Feldt, Felix Dobslaw.
