What is the formula for cyclomatic complexity?

3) Cyclomatic complexity V(G) = P +1 V (G) = 2 + 1 = 3 Where P is predicate nodes (node 1 and node 2) are predicate nodes because from these nodes only the decision of which path is to be followed is taken. Thus Cyclomatic complexity is 3 for given code.

What is cyclomatic complexity in testing?

Cyclomatic complexity is a software metric used to indicate the complexity of a program. It is a quantitative measure of the number of linearly independent paths through a program’s source code. It was developed by Thomas J. McCabe, Sr. in 1976.

What is cyclomatic complexity and how it is calculated?

Cyclomatic complexity is a source code complexity measurement that is being correlated to a number of coding errors. It is calculated by developing a Control Flow Graph of the code that measures the number of linearly-independent paths through a program module.

How is code complexity calculated?

To calculate the cyclomatic complexity of our code, we use these two numbers in this formula: M = E − N + 2 . M is the calculated complexity of our code. (Not sure why it’s an M and not a C .) E is the number of edges and N is the number of nodes.

How to calculate the cyclomatic complexity of a program?

Lower the Program’s cyclomatic complexity, lower the risk to modify and easier to understand. It can be represented using the below formula: Cyclomatic complexity = E – N + 2*P where, E = number of edges in the flow graph. N = number of nodes in the flow graph. P = number of nodes that have exit points

How is the cyclomatic complexity of Virtusa calculated?

It is calculated by developing a Control Flow Graph of the code that measures the number of linearly-independent paths through a program module. Lower the Program’s cyclomatic complexity, lower the risk to modify and easier to understand. It can be represented using the below formula:

How is McCabe’s cyclomatic complexity graph created?

This metric was developed by Thomas J. McCabe in 1976 and it is based on a control flow representation of the program. Control flow depicts a program as a graph which consists of Nodes and Edges. In the graph, Nodes represent processing tasks while edges represent control flow between the nodes.

How is cyclomatic complexity used in white box testing?

Cyclomatic Complexity is software metric useful for structured or White Box Testing. It is mainly used to evaluate complexity of a program. If the decision points are more, then complexity of the program is more.
