QA:Testcase Modularity module list

Description

This test case will show if modularity is enabled in Fedora and that the system provides basic information about the available modules.

Setup

1. Install any of the Fedora spins, for example Workstation or Server.
2. Log onto the system.
3. Run a terminal application, such as gnome-terminal. The following test will use dnf to work with the modules.

Note: For the time's being, users can work with modules using dnf. In the future, other package managers will be able to deal with it. Until then, do not attempt to test this approach using tools other than dnf.

How to test

1. Check that dnf provides you with a list of all modules available to the system:
   To do so, execute dnf module list. You can also use the --all option, the results should be the same.
   
2. Check that dnf provides you with a list of modules that have been enabled on the system.
   Execute dnf module list --enabled to get the list.
3. Check that dnf provides you with a list of modules that have been disabled on the system.
   Execute dnf module list --disabled to get the list.
4. Check that dnf provides you with a list of modules that are installed on the system.
   Execute dnf module list --installed to get the list.

Expected Results

1. Modularity and modular repositories should be enabled by default. If it for does not work for any reason, the test should be considered a fail.
2. All above commands must run without any errors and they should provide the needed info. If they throw any error, report a bug, and the test fails.
3. dnf module list (--all) lists all modules and provides details, such as stream, version and profile. If this command returns an empty list, the test should be considered a fail.
4. dnf module list --enabled lists all enabled modules. The result can be an empty list, if there are no enabled modules.
5. dnf module list --disabled lists all disabled modules. The result can be an empty list, if there are no disabled modules.
6. dnf module list --installed lists all installed modules. The result can be an empty list, if there are no installed modules.
