Testwell CMT++ and CMTJava are tools for measuring software complexity in C, C++, Java and C#. Cyclomatic complexity = E - N + P The metric tries to capture the number of paths through the code, and thus the number of required test cases. The rule reports a violation when the cyclomatic complexity is more than 25. Cyclomatic complexity is a software metric (measurement) used to indicate the complexity of a program. Tools for Cyclomatic Complexity calculation: Uses of Cyclomatic Complexity: Cyclomatic Complexity in Software Testing. Since that time, others have identified different ways of measuring complexity (e.g. The standard threshold for this complexity is 10 points, so if you have a function with higher complexion than that, you should try to reduce it.It will begin by adding 1 point for the function declaration, after that it will add 1 point for every if, while, for and case. The lower the cyclomatic complexity, the easier the program is to understand (of course, there are exceptions to the rule). Fortunately, there are Java cyclomatic complexity tools that you can configure directly into the Maven build or make part of the testing phase of the CI pipeline. ). Static code analysis tools are typically used to calculate cyclomatic complexity and other code complexity metrics.
