Codacy Badge Codacy Badge Build Status Gem Version

Parses SimpleCov output and submits the result to Codacy


Include the gem in your project

gem 'codacy-coverage', :require => false

In the first line of your spec_helper initialize the reporter:

require 'codacy-coverage'



To update Codacy, you will need your project API token. You can find the token in Project -> Settings -> Integrations -> Project API.

Then set it in your terminal, replacing %Project_Token% with your own token:

export CODACY_PROJECT_TOKEN=%Project_Token%


To send coverage in the enterprise version you should:

export CODACY_BASE_API_URL=<Codacy_instance_URL>:16006

By default this plugin will not submit results if you run your tests in localhost. If you want to force the submission you can setup the following environment variable:

export CODACY_RUN_LOCAL=true

Note: You should keep your API token well protected, as it grants owner permissions to your projects.

Running Tests

When you run your tests, the plugin will send the coverage info to Codacy.

For example, run the following commands:

gem install bundler
bundle install

This will install the required dependencies. Then just run the tests:

bundle exec rspec

By default, the debug info will be logged into a file. If you want the debug info to be printed to stdout you can:

export DEBUG_STDOUT=true

You can now check your coverage results in the Codacy dashboard of your project.


Cannot send coverage when using VCR

require 'vcr'
VCR.configure do |config|
  # other config options
  config.allow_http_connections_when_no_cassette = false
  config.ignore_hosts 'api.codacy.com'

Cannot generate local simplecov report

Override SimpleCov.formatter by adding both your prefered simplecov formatter and Codacy's formatter. You can also add more options to SimpleCov.start.

require 'simplecov'
require 'codacy-coverage'

SimpleCov.formatter = SimpleCov::Formatter::MultiFormatter.new([

SimpleCov.start do
  add_filter '.gems'
  add_filter 'pkg'
  add_filter 'spec'
  add_filter 'vendor'
