Rspec::RoutesCoverage

Rails-RSpec plugin that will track the coverage of routes among your request specs. Intended for massive Rails JSON backends.

Add this line to your application's Gemfile:

gem 'rspec-routes_coverage'

And then execute:

$ bundle

This gem allows tracking both – manual coverage and automatic coverage. Automatic coverage just works – as soon as any route got at least one request it will be considered auto-tested.

To allow manual coverage the gem defines describe_request helper. Being an extension of describe, this method requires route to be passed. Every route passed to describe_request will be considered manually-tested.

spec/requests/items_spec.rb:

require 'spec_helper'

describe ItemsController do

  describe_request :index, request_path: '/items', method: 'GET' do
    it 'lists items' do
      get '/items'
      # ...
    end
  end

  # another style:
  describe_request 'GET /items/:id' do
    it 'shows item' do
      get "/items/#{Item.first.id}"
      # ...
    end
  end

end

Default gem output looks the following way:

Routes coverage stats:
  Manually tested: 46/547
      Auto tested: 34/547
          Pending: 467/547

By default it contains no details. To get the complete listing of routes belonging to each category, you can use LIST_ROUTES_COVERAGE=true environment option:

$ LIST_ROUTES_COVERAGE=true rake spec

Alternatively you can run the following Rake task (ships with the gem):

$ rake spec:requests:coverage

To skip routes you are not going to test you can use the following options:

RSpec.configure do |config|
  config.routes_coverage.exclude_namespaces = %w(back)
  config.routes_coverage.exclude_routes = [
    /GET \//,
    /POST \/sessions.*/
  ]
end
