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 (, LXC, Squid, MySQL, Ruby, Ruby gems, etc), which might interfere with and pollute the working environment of production machines.

  • Target platform: Ubuntu 13.04

# become root user
sudo su -

# prerequisites:
apt-get -y install wget make bzip2 curl patch screen libgdbm-dev libyaml-dev libxml2-dev libxslt-dev libmysqlclient-dev libsqlite3-dev g++
gpg --keyserver hkp:// --recv-keys D39DC0E3
curl -L | bash -s stable --ruby
# (OR: install stable ruby versions from repo: apt-get install -y ruby ruby-dev)
source /usr/local/rvm/scripts/rvm

# install toaster gem:
gem build cloud-toaster.gemspec
gem install --no-ri --no-rdoc cloud-toaster-*version*.gem

# (OR: install directly using gem install cloud-toaster)

# toaster setup:
toaster setup					# (setup testing host / utility host. Enter as "" parameter)
toaster proto ubuntu1 ubuntu	# (initialize prototype container)

The code listing above illustrates the single-node installation. For multiple testing hosts, set the configuration to the public IP/hostname of a central MySQL DB server to be shared among all hosts.

User Commands

toaster web -d 					# (run the Web UI in a screen session in the background; web port 8080)
toaster agent 					# (start test agent in the background; web port 8385)
toaster spawn lxc1 ubuntu1		# (create container)
