How are you running your tests with Gulp? I came up against this issue recently on OSX, running node <code>v0.11.14</code> and gulp <code>3.8.10</code>, whenever there were failing tests.

Changing from the recommended:

<pre><code>gulp.task('test', function(done) {
 karma.start({
 configFile: __dirname + '/karma.conf.js',
 singleRun: true
 }, done);
});
</code></pre>

To:

<pre><code>gulp.task('test', function(done) {
 karma.start({
 configFile: __dirname + '/karma.conf.js',
 singleRun: true
 }, function() {
 done();
 });
});
</code></pre>

...got rid of this error.

Seems to be down to how gulp handles error messages when an error is signalled in a callback. See <a href="https://github.com/gulpjs/gulp/issues/587">Improve error messages on exit</a> for more information.

blocks|key|146259|text|这是gulp告诉你的测试已经失败了，并且karma退出，返回代码为1的方式。为什么你想自己调用done，而不将错误作为消息传递给我呢？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|146260|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

this is gulp's way of telling your tests have failed and that karma exited with a return code of 1. Why you would want to call done yourself and not pass the error as a message baffles me.

blocks|key|2723009|text|根据Karma的文档和https://github.com/pkozlowski-opensource，解决这个问题的正确方法是依靠Karma的手表机制，而不是Gulp的：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2723010|gulp.task('tdd',+function+(done)+{

The right way to solve this according to Karma's documentation and <a href="https://github.com/pkozlowski-opensource" rel="nofollow">https://github.com/pkozlowski-opensource</a>, is to rely on Karma's watch mechanism rather than Gulp's:

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

Note the omission of <code>singleRun: true</code>.

@McDamon's workaround will work for <code>gulp.watch</code>, 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 <a href="https://github.com/gulpjs/gulp/issues/71" rel="nofollow">https://github.com/gulpjs/gulp/issues/71</a> and the other dozen or so related issues.

Below is a code snippet from gulp patterns on using Karma. It's a bit similar, but also uses the newer method how to start the karma.

<pre><code>/**
 * Start the tests using karma.
 * @param {boolean} singleRun - True means run once and end (CI), or keep running (dev)
 * @param {Function} done - Callback to fire when karma is done
 * @return {undefined}
 */
function startTests(singleRun, done) {
 var child;
 var excludeFiles = [];
 var fork = require('child_process').fork;
 var KarmaServer = require('karma').Server;
 var serverSpecs = config.serverIntegrationSpecs;

 if (args.startServers) {
 log('Starting servers');
 var savedEnv = process.env;
 savedEnv.NODE_ENV = 'dev';
 savedEnv.PORT = 8888;
 child = fork(config.nodeServer);
 } else {
 if (serverSpecs &amp;&amp; serverSpecs.length) {
 excludeFiles = serverSpecs;
 }
 }

 var server = new KarmaServer({
 configFile: __dirname + '/karma.conf.js',
 exclude: excludeFiles,
 singleRun: singleRun
 }, karmaCompleted);
 server.start();

 ////////////////

 function karmaCompleted(karmaResult) {
 log('Karma completed');
 if (child) {
 log('shutting down the child process');
 child.kill();
 }
 if (karmaResult === 1) {
 done('karma: tests failed with code ' + karmaResult);
 } else {
 done();
 }
 }
}

passing <code>singleRun: false</code> argument will prevent the process from returning a value different of 0 (which would signify an error and exit gulp).

Run with <code>singleRun: true</code> if you only launching your test from a command line, not part of a continuous integration suite.

What worked for me and gave a nice formatted error message is to provide an Error instance to the <code>done</code> callback.

<pre><code>gulp.task('test', function(done) {
 karma.start({
 configFile: __dirname + '/karma.conf.js',
 singleRun: true
 }, function(result) {
 if (result &gt; 0) {
 return done(new Error(`Karma exited with status code ${result}`));
 }

 done();
 });
});
</code></pre>

None of these solutions worked correctly for me using gulp 3.9.1 and karma 1.1.1. Adding a reference to gulp-util <code>npm install --save-dev gulp-util</code> and updating the task to the below fix the error output very nicely, while maintaining exit status correctly.

<pre><code>var gutil = require('gulp-util');

gulp.task('test', function (done) {
 new Server({
 configFile: __dirname + '/karma.conf.js',
 singleRun: true
 }, function(err){
 if(err === 0){
 done();
 } else {
 done(new gutil.PluginError('karma', {
 message: 'Karma Tests failed'

 }
 }).start();
});
