Test coverage using Devel::Cover

cover --test

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.
