Yes, there are coverage tools for Curl, but are not well integrated into the IDE
at the current time and are not fully supported.  You can get coverage
information in a number of ways:

  1) Use --coverage flag with 'curl' executable when running a Curl script.
e.g.:

         > curl --coverage all my-script.xcurl

  2) Run the script using the coverage-viewer.xcurl script, which ships with the
IDE,
     for a graphical display:

         > curl coverage-viewer.xcurl --all my-script.xcurl

     This can also be used to view previously collected data.

  3) Roll your own using contents of the CURL.COVERAGE.DATA and
CURL.COVERAGE.INSTRUMENT
     packages.

You can also use the tool to count the number of times each coverage point was
hit.
