I'm getting two warnings when I run rake test in the master branch.
Could anybody fix these warnings please?

Hello,
I am looking to make my first open source contribution. Is this a good issue to work on?
@aamarill sure, why not?
Feel free to fork the project to your profile and pull it to your computer. After that you can create a Pull Request and start committing there. Run bundle install to install the gems and run rake test to find the warnings. Once it's done, you can push and open a PR in our repository.
Thank you @vbrazo I'll get on it ASAP
@aamarill I had free time and fixed the warnings today. I'm going to assign you another task, ok? 馃憤
@vbrazo No worries!
I am actually pretty free now, so if you have any "newbie-friendly" issues available, send them my way!

@aamarill You can filter the issues.
Here I'm filtering by Bug/Fixes. You could also filter by Feature Request, Documentation and others.
Go there, read the issues. I'm pretty sure that you'll find someone who needs help or an issue that is open just waiting for you. Message people. Make noise 馃憤
@vbrazo Will do! Thanks!! 馃
