Jacoco Coverage formula

[Marc Pires]

Hi everyone, where can I find the formula Jacoco uses to calculate the Coverage. What I am looking for is the actual formula, not only the metrics it uses.

Looking at https://www.jacoco.org/jacoco/trunk/doc/counters.html could not find the related information

Comparing to how SonarQube calculates coverage we have.

 Coverage = (CT+CF+LC)/(2*B+EL)

CT+CF =  (Conditions to Cover -  Uncovered Conditions)

LC =  ( Lines to Cover -  Uncovered Line)

2*B =  (Conditions to Cover already represents the product)

EL =  ( Lines to Cover)

Thanks

Hi Marc,

there is no “formula” besides what is defined here: https://www.jacoco.org/jacoco/trunk/doc/counters.html

JaCoCo reports just show these counters.

I recently learned that Sonar calculates a proprietary metric based on the counters, but this is not what we do in JaCoCo reports.

Best regards,
