Does JaCoCo support velocity

Does JaCoCo support velocity so I can check what branch coverage in code I changed?

Hi,

sorry for my stupid question: What do you mean by "velocity"?

Coverage on changed code is supported in combination with SonarQube.

Let me provide with example:

You have code with 4 branches and 3 or them is covered so branch coverage is 3/4 = 75%. Then you make a change and added 2 branches with just 1 branch covered. So velocity coverage is 1/2 = 50% and my question is if JaCoCo supports that metric?
It's kind of diff coverage.

Hi,

JaCoCo does not support any coverage comparison between different
versions of source code.

As mentioned before SonarQube supports code coverage on changed code
(with JaCoCo). You might ask them whether this specific feature is
available: http://www.sonarqube.org/get-support/
