How do you make custom GitHub shields that track status on your repository?
I am using shields.io and have figured out how to use a Jenkins plugin to expose the build status and create a shield, but wondering how others automate status for code coverage, documentation coverage, linting, unit tests, etc?
Code coverage, linting, etc. are provided by various services that you have to sign up with. For example, coveralls.io provides test coverage. Another popular service that provides many different types of code analysis and coverage tools is Code Climate. Most of those sites provide badges you can add to your GitHub repo, usually in the README.
For example, a repo I maintain has accounts with Travis, Gemnasium, and Code Climate, and I have badges for those services on my README: https://github.com/monfresh/ohana-sms
