Simplecov Rcov Formatter Text

The target of this formatter is to cheat on metric_fu so it's possible to use simplecov instead rcov.

Install

gem install simplecov-rcov-text

Usage

Add the gem to the Gemfile preferably in the group test:

gem 'simplecov', :require => false
gem 'simplecov-rcov-text', :require => false

Create a .metrics file in the root of project with the code:

MetricFu::Configuration.run do |config|
  config.rcov[:external] = 'coverage/rcov/rcov.txt'
end

And follow the instructions of Simplecov and metric_fu or metrical.

Simplest way

require 'simplecov'
require 'simplecov-rcov-text'
SimpleCov.formatter = SimpleCov::Formatter::RcovTextFormatter

Using with HTML Format

require 'simplecov'
require 'simplecov-rcov-text'
class SimpleCov::Formatter::MergedFormatter
  def format(result)
     SimpleCov::Formatter::HTMLFormatter.new.format(result)
     SimpleCov::Formatter::RcovTextFormatter.new.format(result)
  end
end
SimpleCov.formatter = SimpleCov::Formatter::MergedFormatter

Running metric_fu/metrical

Be sure that you configured simplecov and simplecov-rcov-text.

Run your test framework, example:

rspec spec

After that you can run the metric_fu/metrical command.

Don't forget to configure .metrics file!


Example of generated file

metric_fu shift the first line
   class SomeClass
     def method_1
       1+1
     end

     def method_2 ( value )
!!     value * value
     end
   end
