Lab note What I wrote down while learning this by building with it. Short by design; the code is in pfeilbr/node-coveralls-playground.

To learn and experiment with coveralls test coverage service.

Setup Steps

  1. Install deps

    $ npm install mocha coveralls mocha-lcov-reporter --save-dev

  2. Install istanbul

    $ npm install istanbul --save-dev -g

  3. If running from command line, ensure .coveralls.yml is in current directory. It should contain a line with repo_token: REPO_TOKEN

Running

To run on the tests in the test/ directory.
