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-cov-reporter": ">=0.0.1"
Then call mocha with:
mocha --reporter mocha-teamcity-cov-reporter test
This also works well with grunt-mocha-test
