Compatipede is a website compatibility check framework/infrastructure

The General idea is to have several webcompat processes running listening to a RabbitMQ service, from which they are fed with URLs.

A URL is then opened once using the Firefox UserAgent and another time using the WebKit UserAgent and checked for compatibility:

• Equal redirects
• CSS style compatibility
• Source code compatibility
• Other custom tests

Resuls of each run are written to a MongoDB

Automating Compatibility

For now this only runs on Linux machines.

The requirments for this service to run are:

• gir1.2-webkit-3.0
• gir1.2-soup-2.4
• xvfb
• gobject-introspection
• python-dbus
• dbus-x11
• rabbitmq-server
• mongodb-server

To install them all, run

sudo apt-get install gir1.2-webkit-3.0 gir1.2-soup-2.4 xvfb gobject-introspection python-dbus dbus-x11 rabbitmq-server mongodb-server

It is recommended to run it on Ubuntu 13.04 or higher.

In addition, the following Python modules must be available:

• tinycss
• pika
• pymongo

They can all be installed with pip:

sudo pip install tinycss pika pymongo

python webcompat.py listen

sets up a process that will handle a queue of URLs, run tests and store data. To add URLs to the queue, do this in a separate terminal window:

python webcompat.py push http://example.com
