Using git-submodules to version-control Vim plugins

If you work across many computers (and even otherwise!), it's a good idea to keep a copy of your setup on the cloud, preferably in a git repository, and clone it on another machine when you need. Thus, you should keep the .vim directory along with your .vimrc version-controlled.

But when you have plugins installed inside .vim/bundle (if you use pathogen), or inside .vim/pack (if you use Vim 8's packages), keeping a copy where you want to be able to update the plugins (individual git repositories), as well as your vim-configuration as a whole, requires you to use git submodules.

Creating the repository

Initialize a git repository inside your .vim directory, add everything (including the vimrc), commit and push to a GitHub/BitBucket/GitLab repository:

cd ~/.vim

Rules for good testing

Look at the following image...

...it shows an object being tested.

You can't see inside the object. All you can do is send it messages. This is an important point to make because we should be "testing the interface, and NOT the implementation" - doing so will allow us to change the implementation without causing our tests to break.
