Hello, i find some problem when test file has some error.
And this will break karma test task.

PhantomJS 1.9.8 (Linux 0.0.0) ERROR
  ReferenceError: Can't find variable: alter
  at /home/vagrant/github/karma_test/src/hello_src.js:12

And i find the problem.
link this https://github.com/matthias-schuetz/karma-htmlfile-reporter/blob/master/index.js#L87

this.onBrowserComplete = function(browser) {
    var suite = suites[browser.id];
    var result = browser.lastResult;

    suite['results'].txt(result.total + ' tests / ');
    suite['results'].txt((result.disconnected || result.error ? 1 : 0) + ' errors / ');
    suite['results'].txt(result.failed + ' failures / ');
    suite['results'].txt(result.skipped + ' skipped / ');
    suite['results'].txt('runtime: ' + ((result.netTime || 0) / 1000) + 's');

    if (allMessages.length > 0) {
        suite.ele('tr', {class:'system-out'}).ele('td', {colspan:'3'}).raw('<strong>System output:</strong><br />' + allMessages.join('<br />'));
    }
  };

here suite is undefined.
And i think we should test it before use just using if statement.

Sorry for the late response, I've tested and added your code changes, it works!
Thanks for your attention.
