analysis tool that can measure coverage upon executing specific tests. Eclipse may also be able
to do the same using the EclEmma plugin.

Test coverage reporting used to be possible with JaCoCo when Elasticsearch was using Maven
as its build system. Since the switch to Gradle though, this is no longer possible, seeing as
the code currently used to build Elasticsearch does not allow JaCoCo to recognize its tests.
