Fabric can consolidate commands for automated deployment or multi-host operations into a script to reduce manual operations. The above was written after I first touched this thing today. It is indeed very practical. Run fab deploy.

The main logic is to run the unit test on the local dev branch, submit it to the server, log on to the server via ssh, run the pull command, run the unit test, and restart apache2. The first write may be relatively simple and will be continuously improved.

Use Vagrant and Fabric for Integration Testing
