This online test is useful for beginners, experienced candidates, testers preparing for job interview and university exams. The number of paths can be infinite if the program has a backward branch, and cyclomatic measure is built on the number of basis paths through the program. According to the formulas given in (1),(2) and (3), option B is incorrect, because V(G)=E-N+2 and not N-E+2. Function Point (FP) is an element of software development which helps to approximate the cost of development early in the process. 2.McCabe's cyclomatic complexity measure is computed as follows: V = e - n + 2 or V = 1 + d where e = number of edges; n = number of nodes; d = number of decision points. Explanation: Cyclomatic Complexity tells us about the number of independent paths in a program which is covered in white box testing. False ANSWER : a 9 : Condition testing is a control structure testing technique where the criteria used to design test cases is that they. It is a quantitative measure of independent paths in the source code of a software program. It is calculated by developing a Control Flow Graph of the code that measures the number of linearly-independent paths through a program module. Counting Function Point (FP): Step-1: F = 14 * scale. In nearly every audience we present our analysis and quality management tool to, there is at least one person asking whether we also measure Cyclomatic Complexity. 42.
