https://github.com/visionmedia/mocha/wiki/Third-party-reporters describes using third party reporters in mocha.

Basically, have your project's package.json be like:

{
  "devDependencies": {
    "mocha-teamcity-reporter": "0.0.1"
  }
}

Then call mocha with:

mocha --reporter mocha-teamcity-reporter test
