Test coverage using Devel::Cover
Once we know that our tests are passing we could check which lines are exercised in the code during the test execution. For this we can use Devel::Cover by Paul Johnson. First we need to run the tests again now instrumenting with Devel::Cover. This will be much slower than the regular execution but in the end we will get a text report and we will be able to build a nice HTML report with drill down about all the code we ran.
All tests successful. Files=11, Tests=2078, 50 wallclock secs
