How to get per-test coverage for a given project?

[Echo]

Hello, all

I want to get per-test coverage for a project. For example, given a project with 100 junit test cases form GitHub, i need the coverage information for each test case, which is important in the field of Regression Test Case Prioritization. Does Jacoco have such feature? Or what i should do to to implement it? 

Thank you!

Hi,

per test coverage is not supported by JaCoCo. With a good understanding how JaCoCo works you might be able to build something for your scenario. Search this mailing list for previous discussions on this topic.

If it is a maven project just do -Dtest=Classname#methodname for each and post process the results

HI, 

Thank you for your reply. I'm new at this. Please don't mind.

I have gotten  per test coverage with SonarQube following https://deors.wordpress.com/2014/07/04/individual-test-coverage-sonarqube-jacoco/

The jacoco.exec file when using sonar-jacoco-listeners stores the coverage information for Individual Tests, doesn't it?
