Hi Prakash,
The concept of Coverage has been streamlined and simplified in SonarQube v6.x. This does mean, for example, that there are no more dedicated metrics for each test type. Note that this is mentioned in the Release 6.2 Upgrade Notes (more details there).
At a high-level the idea really is to position SonarQube as a consolidator of all the possible coverage data you may wish to import (in a flexible/scalable way). That evolution also allows to track 0 coverage on files that have executable code without associated coverage data. And ultimately it lets each underlying tool reports their specific suite/results in the most suitable manner (and you should consult those reports if you want a more fine-grained view into coverage results).
