transmute-ruby

Transmute

Ruby gem to help you to generate the reverse-coverage relationship between code and tests. The output is a .transmute.json file with key as source code + line and the value is an array with all specs that touch this particular line.

Installation

Add this line to your application's Gemfile:

gem "transmute-ruby"

And then execute:

$ bundle install

Or install it yourself as:

$ gem install transmute-ruby

Usage

require "rspec"
require "transmute"

RSpec.configure do |config|
  config.before(:suite) do
    Transmute.start if ENV["COVERAGE"]
  end

  config.around do |example|
    example.run
    Transmute.add_coverage(example) if ENV["COVERAGE"]
  end

  config.after(:suite) do
    Transmute.store! if ENV["COVERAGE"]
  end
end

Test

We prioritize end-to-end tests, so you'll not see spec file here. In order to make sure that everything is working properly, you should add rust specs in the engine folder.
