Basis path testing, a structured testing or white box testing technique used for designing test cases intended to examine all possible paths of execution at least once. It is a quantitative measure of the number of linearly independent paths through a programs source code. There are several different basis sets for the given algorithm. A simple path is a path in which any node cant appear more than once but only starting and ending nodes can appear more than once. Although many different types of testing exist such as data flow and equivalence class testing, this paper is going to concentrate on one particular method.
