Koality

Runs opinionated code metric tools against your code as part of the test suite. If the set level of desired quality is not met the build will fail.

Beware of the drop bears.

Installation

Add this line to your application's Gemfile:

gem 'koality', :require => false

And then execute:

$ bundle

Or install it yourself as:

$ gem install koality

Usage

Add the following to your applications Rakefile. Place it after MyApp::Application.load_tasks for Rails apps.

begin
  require 'koality/rake_task'

  Koality::RakeTask.new do |opts|
    # configure options here
    # See [koality_home]/lib/koality/options.rb for defaults

    # opts.abc_threshold = 10
  end
  task :default => :koality
rescue LoadError
  warn 'Could not load Koality, skipping Rake task.'
end

Running your test suite with Koality:

rake

Running koality on its own:

rake koality 

SimpleCov Integration (Optional)

Add the following to the top of your spec/spec_helper.rb file. Must be before your require your application code.

require 'koality/simplecov'
SimpleCov.start

All options are shown with their current defaults.

Configuring Rails Best Practices

Generate the config file (config/rails_best_practices.yml)

bundle exec rails_best_practices -g

Edit configuration or comment out lines to skip certain checks.

Common Questions

  • I don't want to the build to fail if I exceed any thresholds. How do I turn that off?

      opts.abort_on_failure = false
    
  • I only want to fail the build if there are over 10 ABC errors. How do I set that up?

      opts.abc_violations_threshold = 10
      opts.total_violations_threshold = -1
    
  • How do I keep style violations from breaking the build?

    opts.style_violations_threshold = -1
    opts.total_violations_threshold = -1
