Documentation inconsistency for cyclomatic complexity metrics

[anand sudhan]

Hello Folks,

For explanataion on Sonarqube cyclomatic complexity metrics - I found this link.

I used a Sonarqube 5.6.6 server, with Javascript plugin 2.20 and Java Plugin 4.5.

On testing Java and Javascript plugins I found the following inconsistencies:

• For Java:
• return statements not counted as +1 anymore (this is the non- last return statements of a method)
• catch and throw statements are not counted as +1 anymore
• For Javascript:
• return statments not counted as +!
• throw is not counted as +1
• function expression is not considered as +1

I couldn't find release notes references for the plugins that corresponded to these changes in behaviour of the plugins( I was using Java 3.0 and Javascript 2.8 before).

Kindly update the documentation link for cyclomatic complexity metrics - if it is obsolete.

Thanks,

Anand

Hi Anand,

Thanks for bringing this to our attention. I've updated the documentation. Here are the relevant tickets:

https://jira.sonarsource.com/browse/SONARJAVA-75

Hi Ann,

Thanks for the swift response. There are couple more corrections:

• Typo here in Java section ", (that is not the last statement of a method)" - you can delete this - as it was associated with return statements
• Also Catch statements dont add to complexity in Java - that is based on my testing - you may want to consider removing catch also from the Java section.

Thanks! - Anand
