I don't know whether somebody creates a QTP implementation yet. Probably
one would use the JaCoCo agent remote capabilities and request dumps
from the QTP test runner.
In any case implementing this required a good understanding of the
JaCoCo APIs as well as of the QTP platform. Please understand that the
JaCoCo project itself cannot provide integrations for proprietary
product. Maybe you can request such a feature by the QTP vendor HP.
