title: How to do unit test coverage in Erlang
body: <p>When using Python I do test code coverage with tools like python-coverage and especially for django the package djaango-nose, I'm looking for an equivalent in Erlang. I already do tests with <a href="http://erlang.org/doc/man/eunit.html">eunit</a> and generate my reports with <a href="http://erlang.org/doc/man/eunit_surefire.html">surefire</a> but I didn't find a way to do code coverage, does anyone know tools or methodology to do this ?</p>
