one_hundred_percent_coverage¶ ↑

Useful lil gem to ensure 100% coverage of your tests. It uses the excellent gem “simplecov” and only works for Ruby 1.9 (I think).

When included in your specs, it will output the HTML report to the “coverage” directory.

In your Gemfile…

gem 'one_hundred_percent_coverage', :group => :test

On the command line…

gem install one_hundred_percent_coverage

In the spec helper (usually spec/spec_helper.rb), add…

require 'one_hundred_percent_coverage'

Now tests will fail if they do not have 100% coverage.

Personally, I tend to include it in my spec_helpers conditionally, so single test runs aren’t affected. I do something like…

require 'one_hundred_percent_coverage' if ENV['with_coverage']

• Ruby 1.9

• simplecov
