Semaphore is a popular continuous integration service that supports a wide range of programming languages. Up-to-date versions of Firefox, PhantomJS and Node.js make it a good testing ground for JavaScript applications. This article assumes you already have a Semaphore account.

Configure Your Project

If you do not already have a package.json in your project root, create one now. This will both document your configuration and make it easy to run your tests. Here's an example:

// ...snip...
"devDependencies": {
  "karma": "~0.10"
},
// ...snip...
"scripts": {
   "test": "./node_modules/.bin/karma start --single-run --browsers PhantomJS"
}
// ...snip...

Another option is to use Firefox as your test browser. To do this, change the last part to:

"scripts": {
   "test": "./node_modules/.bin/karma start --single-run --browsers Firefox"
}

Now running npm test within your project will run your tests with Karma.

Add Your Project to Semaphore

Follow the process as shown in the screencast on the Semaphore docs.

After the analysis is finished, ignore the Ruby version Semaphore has set for you, choose to customize your build commands and use these:

npm install
npm test

That's it - proceed to your first build. In case you're using Firefox as your test browser, Semaphore will automatically run it on a virtual screen during your builds.

Also, if necessary, build commands can be further customized at any time.
