A modified version of the QUnit Team City output. Needed to add a special variable to track the beginning and end of a module because testSuiteFinished were being misplaced or duplicated. Needed to escape the test names in order to use apostrophes. Also added a snippet that sets up window.console.log() as a blank function when it's not present. …

qunit.teamcity.js

(function (QUnit) {

    if (!window.console) {
        window.console = {
            log: function () { }
        };
    }

    var tcEscape = function (str) {
        str = str ? str.toString() : "";
        str = str.replace(/\n/g, "|n");
        str = str.replace(/\r/g, "|r");
        str = str.replace(/(['\[\]])/g, "|$1");
        return str;
    };

    var suiteRunning = false;

//QUnit.moduleStart({ name })
    QUnit.moduleStart = function (settings) {
        console.log("##teamcity[testSuiteStarted name='" + settings.name + "']");
        suiteRunning = true;

    QUnit.moduleDone = function (settings) {
