TestSwarm - Distributed Continuous Integration for JavaScript

TestSwarm provides distributed continuous integration testing for JavaScript.

The main instance monitoring jQuery core and related projects runs at swarm.jquery.org.

Project Status

TestSwarm is still in use in projects of the jQuery Foundation, but it isn't under active development anymore. Although critical issues may be patched in the future, most open issues will remain unaddressed.

Within the jQuery Foundation, we're experimenting with alternative projects, to eventually shut down our own instance of TestSwarm:

We recommend reviewing those and other alternatives.

Quick start

Clone the repo, git clone --recursive git://github.com/jquery/testswarm.git.


TestSwarm uses the Semantic Versioning guidelines as much as possible.

Releases will be numbered in the following format:


The -alpha suffix is used to indicate unreleased versions in development.

Environmental compatibility

To run TestSwarm you will need a web server, a database server and PHP. At the moment TestSwarm supports the following, but other configurations may work as well.

  • Apache 2.0+, NGINX 1.2+
  • PHP 5.4+ (or PHP-FPM for NGINX)
  • MySQL 4.0+
  • cURL (for the cleanup action; see step 8)


  1. Create an empty MySQL database and create a user with read and write access to it.

  2. Copy config/sample-localSettings.php to config/localSettings.php
    Copy config/sample-localSettings.json to config/localSettings.json.
    Edit localSettings.json and replace the sample settings with your own.
    Refer to the Settings page for more information.

  3. For Apache:
    Copy config/sample-.htaccess to .htaccess.
    To run TestSwarm from a non-root directory, set web.contextpath in localSettings.json to the correct path from the web root and update RewriteBase in .htaccess. Verify that .htaccess is working properly by opening a page other than the HomePage (e.g. /testswarm/projects) in your browser.
    Required Apache configuration:

    • AllowOverride is set to All (or ensure FileInfo is included).
    • mod_rewrite installed and loaded.

    For NGINX:
    Copy config/sample-nginx.conf to /etc/nginx/sites-available.
    The file name should match your domain e.g. for swarm.example.org:
    cp config/sample-nginx.conf /etc/nginx/sites-available/swarm.example.org.conf
    Open this conf file in your editor and replace the "example" values with the correct values.
    Make sure your install is located at /var/www/testswarm (otherwise update the file to match the correct location).
    Now you need to link the sites-available config to the sites-enabled config:
    (replace the "swarm.example.org" with your own file name):
    ln -s /etc/nginx/sites-available/swarm.example.org.conf /etc/nginx/sites-enabled/swarm.example.org.conf
    Now make sure that php-fpm is running: /etc/init.d/php-fpm status
    if is not running start it: /etc/init.d/php-fpm start

  4. Copy config/sample-robots.txt to robots.txt
    Or, if TestSwarm is not in the root directory, add similar rules to your root robots.txt.

  5. Set storage.cacheDir to a writable directory that is not readable from the web. Either set it to a custom path outside the document root, or use the default cache directory (protected with .htaccess).
    Chmod it: chmod 777 cache.

  6. Install dependencies composer install

  7. Install the TestSwarm database by running: php scripts/install.php

  8. Create an entry in your crontab for action=cleanup. This performs various cleaning duties such as making timed-out runs available again.
    * * * * * curl -s http://swarm.example.org/api.php?action=cleanup > /dev/null

  9. Create a project and submit jobs.
