SimpleCovBadge is a gem that can be added to the Gemfile and will produce a file called coverage_badge.png in the coverage directory. It could be looking as follows dependent on how it is configured.

The idea is to created a badge for SimpleCov to create a persistable image that shows the coverage in percent as a badge.

The badge creation is dependent on the Repo-small-badge gem which creates and SVG badge. It can be installed in your Ruby library or rails app as part of the Gemfile as follows.

# In your gemfile
gem 'simplecov-small-badge', :require => false

This gem is an alternative and inspired by the great work in the other gem simplecov-badge which does a similar badge but looks different and cannot easily made small. So it's mostly an optical alternative.

Whereever you are integrating SimpleCov you can configure the SimpleCovSmallBadge gem as any formater can be configured. The default integration could looks as follows:

require 'simplecov_small_badge'

# Wherever your SimpleCov.start block is (spec_helper.rb, test_helper.rb, or .simplecov)
SimpleCov.start do
  # add your normal SimpleCov configs
  add_filter "/app/model"
  # call SimpleCov::Formatter::BadgeFormatter after the normal HTMLFormatter
  SimpleCov.formatters = SimpleCov::Formatter::MultiFormatter.new([
    SimpleCov::Formatter::HTMLFormatter,
    SimpleCovSmallBadge::Formatter
  ])
end

# configure any options you want for SimpleCov::Formatter::BadgeFormatter
SimpleCovSmallBadge.configure do |config|
  # does not created rounded borders
  config.rounded_border = true
  # set the background for the title to darkgrey
  config.background = '#ffffcc'
end

This process is split into two steps.

1. You need to create an access token for you github repository that can be configured to travis to allow password-less pushing. This is described in Github Help - Authenticating to GitHub / Creating a personal access token for the command line

2. Configure travis to push the result to github-pages inspired from the Travis description and configuration to be found in .travis.yml

3. Integrate your badge into the README.md as follows ![Coverage](https://marcgrimme.github.io/simplecov-small-badge/badges/coverage_badge_total.png)

The behaviour of SimpleCovSmallBadge can be influenced by configuration options as defined in the configuration class.
