Rob S. - MultiRails lead

MultiRails lets you test your Rails plugin or app against many
versions of Rails in one sweep.

== URLs:

rubyforge: http://rubyforge.org/projects/multi-rails/
rdocs: http://multi-rails.rubyforge.org/
svn stable:
http://robsanheim.googlecode.com/svn/tags/stable/multi_rails (gem is
released from here)
svn trunk: http://robsanheim.googlecode.com/svn/trunk/multi_rails
mailing list: http://groups.google.com/group/multi_rails

== DESCRIPTION:

MultiRails allows easy testing against multiple versions of Rails for
your Rails specific gem or plugin. IT also has tentative support
testing Rails applications against multiple versions of Rails.

Use MultiRails to hook in Rails 2.0 testing in your continuous
integration. Still working on Rails 2.0 support? Use MultiRails to
see where your test suite falls down against the 2.0 preview releases
of Rails.

MultiRails was initially developed by members of Relevance while
developing Streamlined
against edge Rails. To see how Streamlined uses MultiRails, go to
http://trac.streamlinedframework.org.

== FEATURES:

  • easily test plugins/extensions using a require from your
    test_helper.rb and a require in your RakeFile
  • rake tasks to test against a specified version of Rails, the latest
    version, or all versions
  • tentative support for testing plain Rails apps against multiple
    versions of Rails
  • Uses rubygems for version management of Rails

== TODOs:

  • improve docs on how to override what files are required by multi_rails
  • maybe add ability to load plain Rails versions – ie checked out
    copies not in RubyGems

== NOTES:

  • (For Rails apps only) multi_rails will rename your vendor/rails
    directory to vendor/rails.off if it finds one within your rails app.
    We have to do this to make Rails fall back to RubyGems rails.
    Multi_rails will rename back to the correct vendor/rails when done
    testing, so it will not interrupt your app in normal use.
  • (For Rails apps only) multi_rails needs to add a line to top of
    your environment.rb to hook into – see the instructions below for
    more details

== REQUIREMENTS:

  • Ruby 1.8.5 or higher
  • Rubygems
  • Rails 1.2.1 or higher
  • at least one copy of Rails installed via rubygems.

== INSTALLING FOR RAILS APPS

  • install the plugin, which will copy the multi_rails_runner into your
    script folder on install.
    script/plugin install
    http://robsanheim.googlecode.com/svn/tags/stable/multi_rails

  • Run the multi_rails bootstrap command to get your Rails app ready to
    go with multi_rails - this will add a require line to the top of your
    environment.rb needed for multi_rails to work right.
    script/multi_rails_runner bootstrap

  • Run your tests against all versions of Rails installed (the default):
    script/multi_rails_runner
    or run our tests against the most recent version of Rails you have
    installed:
    script/multi_rails_runner latest
    or just a specific version:
    MULTIRAILS_RAILS_VERSION=1.2.5 script/multi_rails_runner one

== INSTALLING FOR PLUGINS

  • Install multi_rails
    sudo gem install multi_rails

  • In your projects Rakefile, require the multi_rails Rake tasks.

    require “load_multi_rails_rake_tasks”

  • Run rake -T to verify you see the multi_rails tasks.
    rake -T multi_rails

    should see "rake test:multi_rails:all, rake

test:multi_rails:latest…etc"

  • In your test_helper, require multi_rails_init before any rails
    specific requires (activerecord, actioncontroller, activesupport,
    etc).

    require ‘multi_rails_init’

  • Run the multi_rails:all rake task to run your test suite against all
    versions of Rails you have installed via gems. Install other versions
    of Rails using rubygems to add them to your test suite.

  • For changing the Rails version under test, set the environment
    variable MULTIRAILS_RAILS_VERSION to version you want, and run the
    multi_rails:one task or just run a test class directly.

== HELP

  • Join the mailing list!
    http://groups.google.com/group/multi_rails
    [email protected]

  • Rails plugin testing is pretty solid, but rails app testing is
    still new. Post issues to the mailing list.

  • Getting gem activation errors? Post to the list with how you are
    using multi_rails, and I’ll try to help.
