ToASTER
Automated testing of Infrastructure as Code automation scripts (e.g., Chef).
(ToASTER is an acronym for "Testing of Automation Scripts via Twisted Execution Runs")
Building and Installing
Important note: We highly recommend to install ToASTER only on dedicated machines, e.g., a clean virtual machine from Amazon EC2. Do not install toaster on any production servers or your own development machine! The reasons are twofold: first, toaster requires a high amount of disk space for creating LXC containers, storing test data etc; second, toaster relies on a comprehensive third-party software stack (docker.io, LXC, Squid, MySQL, Ruby, Ruby gems, etc), which might interfere with and pollute the working environment of production machines.
Target platform: Ubuntu 13.04

# toaster setup:
toaster setup # (setup testing host / utility host. Enter 192.168.100.2 as "db.host" parameter)
toaster proto ubuntu1 ubuntu # (initialize prototype container)
The code listing above illustrates the single-node installation. For multiple testing hosts, set the db.host configuration to the public IP/hostname of a central MySQL DB server to be shared among all hosts.
