Vagrant is a tool for building and distributing development environments.
Vagrant provides the framework and configuration format to create and manage complete portable development environments. These development environments can live on your computer or in the cloud, and are portable between Windows, Mac OS X, and Linux.
First, make sure your development machine has VirtualBox
installed. After this, download and install the appropriate Vagrant package for your OS. If you're not on Mac OS X or Windows, you'll need
/opt/vagrant/bin to your
PATH. After this, you're ready to go!
To build your first virtual environment:
vagrant init precise32 http://files.vagrantup.com/precise32.box vagrant up
Note: The above
vagrant up command will also trigger Vagrant to download the
precise32 box via the specified URL. Vagrant only does this if it detects that
the box doesn't already exist on your system.

Installing the Gem from Git
If you want the bleeding edge version of Vagrant, we try to keep master pretty stable and you're welcome to give it a shot. The following is an example showing how to do this:

Dependencies and Unit Tests
To hack on vagrant, you'll need bundler which can
be installed with a simple
gem install bundler. Afterwords, do the following:
bundle install rake
This will run the unit test suite, which should come back all green! Then you're good to go!
If you want to run Vagrant without having to install the gem, you may use
bundle exec bin/vagrant help
Vagrant also comes with an acceptance test suite which runs the system end-to-end, without mocking out any dependencies. Note that this test suite is extremely slow, with the test suite taking hours on even a decent system. A CI will be setup in due time to run these tests automatically. However, it is still useful to know how to run these tests since it is often useful to run a single test if you're working on a specific feature.
The acceptance tests have absolutely zero dependence on the Vagrant
source. Instead, an external configuration file must be used to give
the acceptance tests some parameters (such as what Vagrant version is
running, where the Vagrant
vagrant binary is, etc.). If you want to
run acceptance tests against source, or just want to see an example of
this file, you can generate it automatically for the source code:
This will drop an
acceptance_config.yml file in your working directory.
You can then run a specific acceptance test like so:
ACCEPTANCE_CONFIG=./acceptance_config.yml ruby test/acceptance/version_test.rb
If you're developing an acceptance test and you're unsure why things might be failing, you can also view log output for the acceptance tests, which can be very verbose but are a great help in finding bugs:
ACCEPTANCE_LOGGING=debug ACCEPTANCE_CONFIG=./acceptance_config.yml ruby test/acceptance/version_test.rb
