Purpose
Scope
This PR concerns itself with validation and dispatching of user-provided command line options to zonemaster-cli.
Limitations:
Goal
This PR aims to establish a sufficient regression testing suite for the stated scope. It would be great if we didn't need to perform any manual testing for this particular aspect of the application when switching out the command line parsing library.
Context
As part of #68 we plan to drop our dependency on Moose and MooseX::Getopt::GLD. That will affect every command line option in zonemaster-cli.
Changes
Fixes the handling of invalid --hints argument.
New tests are added for options and option combinations:
To help finding gaps in test coverage I added support for Devel::Cover in usage.t.
This PR also includes some cleanups.
How to test this PR
Unit test should pass.
