`FAQ

This occurs due to lingering event handlers and it is currently an [unsolved
issue][issue-4]. Meanwhile you have to explicitly exit the process yourself.
This can be done by not passing a callback to Karma.Server or by invoking
process.exit(), as shown below.
javascript
var gulp = require('gulp');
var Server = require('karma').Server;gulp.task('test', function () {
new Server({
configFile: __dirname + '/karma.conf.js',
singleRun: true
}).start();
});
`javascript
var gulp = require('gulp');
var Server = require('karma').Server;gulp.task('test', function (done) {
new Server({
configFile: __dirname + '/karma.conf.js',
singleRun: true
}, function (exitCode) {
done();
process.exit(exitCode);
}).start();
});

You might experience a [known issue][issue-27] where Karma attempts to perform
a synchronous request, resulting in a deadlock. Disable use of source-maps in
your tests, as shown below.
// angular.json{
...
"test": {
"options": {
"sourceMap": false
