如何衡量每个开发人员的Java代码单元测试覆盖率？

Question

Scenario: a team works on a Java/Maven/JUnit project using some kind of SCM. We would like to increase test coverage, meaning all developers should test code more intensively. Measuring overall test coverage improvements using something like SonarQube is easy enough, but you need to do it per developer in order to be able to recognise the outliers: engineers which have the best test coverage and engineers whose coverage is worst.

How would you answer the question "what is the test coverage of code modified by developer X during the last month?" Is there a surrogate, approximate measure that could be followed more easily?

有一个商业开发人员Cockpit插件，可以做到这一点，以及其他漂亮的功能。
