What is it?

simplecov

SimpleCov is a code coverage analysis tool for Ruby.

How to use

Install

#Gemfile group :test do gem 'simplecov' end 

Setting

#spec/rails_helper.rb require `simplecov` SimpleCov.start do add_filter %r{/spec/} add_group "Service", "app/services/" end 

Result

Simplecov will make a file at coverage/index.html.

You can see it on your browser.

My use case

Simplecov is also good to check Authorization gems work.

My project was a mess, and there are many wholes of pundit(it's like banken) settings.
