# This is a very quick and dirty attempt to figure some metrics for our tests

# It monitors all qml files with inotifywatch and generates a cobertura

# compatible coverage.xml file containing the statistics. This is far from

# perfect but its a start and indeed gives somewhat meaningful numbers

#

# If this proves to be useful, it probably could/should be rewritten

# in a more robust and flexible way, preferably in a language where

# floating point operations and xml writing is natively supported.
