Understanding Complexity Matric


(Vish S.) #1

In Sonarqube version 6.1 Community Edition, the measures tab for each project shows the matric for complexity.

Could you please let us know what these number means ? and how its calculated?

Complexity :18,576
Complexity /function:5.9

First, the current version of SonarQube is 7.3 (7.4 imminent) and the current LTS. I start with this not just because it’s my favorite old saw, but because it’s really relevant to your question.

In fact, in more recent versions of SonarQube we’ve dropped

Why? Because nobody knows what to do with them; they’re not actionable. We kept “Complexity” but changed to its full name of “Cyclomatic Complexity”. It’s the total, aggregate cyclomatic complexity of all the files in your project.
