Issue running karma task from gulp

Question

I am trying to run karma tests from gulp task and I am getting this error:

Error: 1
   at formatError (C:\\Users\\Tim\\AppData\\Roaming\\npm\\node_modules\\g

The right way to solve this according to Karma's documentation and https://github.com/pkozlowski-opensource, is to rely on Karma's watch mechanism rather than Gulp's:

gulp.task('tdd', function (done) {
  karma.start({
    configFile: __dirname + '/karma.conf.js'
  }, done);
});

Note the omission of singleRun: true.

@McDamon's workaround will work for gulp.watch, but you don't want to swallow exit codes like that when running on a CI server.

Gulp is also reworking how they handle exit codes in scenarios just like this one. See https://github.com/gulpjs/gulp/issues/71 and the other dozen or so related issues.
