A Mocha reporter specifically for Circle CI.

Install the reporter as a development dependency:

npm install mocha --save-dev
npm install mocha-circleci-reporter --save-dev

Update your package.json to use the reporter when running Mocha:

{
  "name": "my-package",
  "version": "0.0.1",
  "scripts": {
    "test": "node_modules/.bin/mocha --reporter mocha-circleci-reporter test/*.js"
  }
}

As of Mocha 2.x, its not possible to use multple reporters out of the box. This complicates things when dealing with CI systems like Circle CI that require a format such as jUnit XML as a lot of the goodness that is written to console when running the default reporter (Spec).

To overcome this, the mocha-circleci-reporter report combines both the builtin Spec and mocha-junit-report reporters.

Example spec output:

Example jUnit output:

There is work underway in Mocha 3.x to move to a plugin architecture that would make multiple reporters dead simple, until then I hope this simplifies things.
