Build Status Coverage Status


Easily configure a npm module to generate and upload tests coverage statistics to Coveralls.io. This module is focused for projects based on mocha as test library, pull-requests to add support for other testing libraries are welcome.

And of course, it's executed against itself! :-D

How to use easy-coveralls in 5 steps

  1. be sure your tests are passing on your CI server and that you has enabled your project on Coveralls.io.

  2. add the easy-coveralls dependency to your project:

    npm install --save-dev easy-coveralls
  3. add a script entry on your project package.json file for the test coverage:

      "scripts": {
        "coveralls": "easy-coveralls"
  4. configure your CI server to exec easy-coveralls. For TravisCI add to your project .travis.yml file:

    - npm run coveralls

    For SemaphoreCI just set npm run coveralls as a Post-Thread script.

  5. Ta-Da! :-D

How it works

First create an instrumented version of your module or library and swap it with the original one. Later exec the tests as usual generating a lcov compatible report in the case your tests works just by executing the mocha command and update the coverture statistics to Coveralls.io, and finally delete the instrumented library and restore your original one. No less, no more.
