## Testing

Before doing anything at all make sure that your ruby version is as specified in
the `.ruby-version` file, and that you have also installed `bundler`. After
that, just run `bundle` to get all the gems as needed.

Then prepare the database:

```sh
$ bundle exec rake db:setup
```

And finally, in order to run unit tests, simply run:

```sh
$ bundle exec rails test
```

System tests can also be run quite simply:

```sh
$ bundle exec rails test:system
```

And finally, make sure that the code follows the proper style:

```sh
$ bundle exec rubocop
```
