Three Awesome Libraries to Assess Code Quality in Ruby

As part of our Rails upgrade business we get to evaluate a lot of codebases every month. We usually need a quick way to assess the quality of the code we get. For this we like to use CodeClimate and SimpleCov.CodeClimate is free for open source projects and paid for private projects. I know that not everybody can pay for their service, so I thought it was a good idea to share some free, open source alternatives.Here is a list of 3 tools that can help you assess the quality of your next codebase.What I like about these tools is that they use other Ruby gems to calculate the complexity of the codebase.I went ahead and created a sample report for each of them. As my test project, I picked e-petitions, an open source Rails application for the UK Government's petitions service.
