Sismo: Your Continuous Testing Server
Sismo is a Continuous Testing Server written in PHP.
Unlike more "advanced" Continuous Integration Servers (like Jenkins), Sismo does not try to do more than getting your code, running your tests, and send you notifications.
What makes Sismo special?
Sismo has been optimized to run locally on your computer for your Git
projects. Even if it can test remote repositories, Sismo is better used as a
post-commit hook. Whenever you commit changes locally, Sismo runs
the tests and give you immediate feedback before you actually push your
modifications to the remote repository. So, Sismo is a nice complement to
your Continuous Integration Server.
Sismo is language and tool agnostic. Just give it a command that knows how to run your tests and returns a non-zero exit code when tests do not pass.
Sounds good? There is more. Sismo is insanely easy to install (there is only one PHP file to download), easy to configure, and it comes with a gorgeous web interface.
Installing Sismo is as easy as downloading the sismo.php file and put it somewhere under your web root directory. That's it, the CLI tool and the web interface is packed into a single PHP file.
Note that Sismo needs at least PHP 5.3.3 to run.
By default, Sismo reads its configuration from
<?php $projects = array(); // create a Growl notifier (for MacOS X) $notifier = new Sismo\GrowlNotifier('pa$$word'); // create a DBus notifier (for Linux) //$notifier = new Sismo\DBusNotifier(); // add a local repository hosted on Github $projects = new Sismo\GithubProject('Twig (Local)', '/Users/fabien/Twig', $notifier); // add a remote Github repository $projects = new Sismo\GithubProject('Twig', 'fabpot/Twig', $notifier); // add a repository accessible via SSH $projects = new Sismo\Project('Twig' 'email@example.com:fabpot/Twig.git'); // add a project with custom settings $sf2 = new Sismo\Project('Symfony'); $sf2->setRepository('https://github.com/symfony/symfony.git'); $sf2->setBranch('master'); $sf2->setCommand('./vendors.sh; phpunit'); $sf2->setSlug('symfony-local'); $sf2->setUrlPattern('https://github.com/symfony/symfony/commit/%commit%'); $sf2->addNotifier($notifier); $projects = $sf2; return $projects;
For notifications, you can also use any Cruise Control "tray" software as Sismo also exposes an XML file in the Cruise Control format:
Build all configured projects by running the
$ php sismo.php build --verbose
If a build fails, Sismo will send notifications. Use the
output command to
see the latest build output of a project:
$ php sismo.php output twig
If you have configured Sismo to be accessible from the web interface, you can also check the build outputs there:
If your web server runs under a different user than the one you use on the CLI, you will need to set some environment variables in your virtual host configuration:
SetEnv SISMO_DATA_PATH "/path/to/sismo/data" SetEnv SISMO_CONFIG_PATH "/path/to/sismo/config.php"
build command is quite powerful and has many options. Learn more by
$ php sismo.php build --help
To make Sismo run whenever you commit some changes, use this
php /path/to/sismo.php --quiet build symfony-local `git log -1 HEAD --pretty="%H"` &
symfony-local is the slug of the project. You can also create a
post-merge script if you want to run Sismo when you merge branches.
Sismo is small and simple and it will stay that way. Sismo will never have the following:
- a queue (if a project is already being built, newer commits are ignored);
- a web interface for configuration;
- metrics support;
- plugin support;
- other SCM support;
- slaves support;
- built-in authentication.
... and probably the feature you have in mind right now and all the ones you will think of later on ;)
Tips and Recipes
Change the default Location
Set the following environment variables to customize the default locations used by Sismo:
# in a .htaccess or httpd.conf Apache configuration file SetEnv SISMO_DATA_PATH "/path/to/sismo/data" SetEnv SISMO_CONFIG_PATH "/path/to/sismo/config.php" # for the CLI tool export SISMO_DATA_PATH=/path/to/sismo/data/ export SISMO_CONFIG_PATH=/path/to/sismo/config.php
Tracking multiple Branches
To track multiple branches of a project, just make their names unique and set the branch name:
$projects = new Sismo\GithubProject('Twig (master branch)', '/Users/fabien/Twig'); $projects = new Sismo\GithubProject('Twig (feat-awesome branch)', '/Users/fabien/Twig@feat-awesome');
Note that Sismo uses the same clone for projects sharing the same repositories URL.
Running Sismo for Remote Repositories
Using Sismo for remote repositories is as simple as adding the Sismo building tool in a crontab entry:
0 12 * * * php /path/to/sismo.php --quiet
For GitHub projects, and other systems that support post-receive URL hooks, you can set up Sismo to build automatically when a new revision is pushed. You need to set an environment variable in your Apache configuration:
# in a .htaccess or httpd.conf Apache configuration file SetEnv SISMO_BUILD_TOKEN "YOUR_TOKEN"
Replace YOUR_TOKEN with something more secure, as anyone with this token could use it to trigger builds. Then set your post-receive URL appropriately. For example:
History in the Web Interface
The build history for a project in the web interface is different from the project history. It is sorted in the order of the builds so that the latest build output is always at your fingertips.
