If you want to return with an error code, and want to see Karma's error output but not Gulp's (probably unrelated) stack trace:

gulp.task('test', function() {
    karma.start({
        configFile: __dirname + '/karma.conf.js',
        singleRun: true
    }, function(karmaExitStatus) {
           if (karmaExitStatus) {
               process.exit(1);
           }
    });
});
